Potential Java SE API compatibility issue. MISRA. V589. V586. Decreased performance. Moving an object in a return statement prevents copy elision. AUTOSAR. It only takes a minute to sign up. AUTOSAR. Generating points along line with specifying the origin of point generation in QGIS. Consider inspecting the loop expression. Suspicious pointer arithmetic with 'malloc/new'. The variable can be constructed in a lower level scope. :' operator, regardless of its conditional expression, always returns one and the same value. V6088. V3093. The 'strlen' function was called multiple times inside the body of a loop. V3142. The left operand of integer division is less than the right one. A 'break' statement is probably missing in a 'switch' statement. If expression is omitted, the return value of the function is undefined. It is possible that this 'else' branch must apply to the previous 'if' statement. The functions from time.h/ctime should not be used. Let's consider an example. V6002. Converting integers or pointers to BOOL can lead to a loss of high-order bits. A new object is created, while a reference to an object is expected. V685. Size of the 'time_t' type is not 64 bits. In case of false, your function will not return anything and result in compilation error. V702. The modulo by 1 operation is meaningless. Cast should not remove 'volatile' qualifier from the type that is pointed to by a pointer or a reference. It is possible that there is an error. Continue with Recommended Cookies. V816. The sizeof() operator returns pointer size instead of array size. The closing tag was encountered, while the tag was expected. V3076. The standard input/output functions should not be used. To tell the compiler that a function does not return a value, a return type of void is used. It is inefficient to identify an empty string by using 'strlen(str) > 0' construct. V729. V1012. V6001. Variable is assigned but not used by the end of the function. It is odd that the body of 'Foo_1' function is fully equivalent to the body of 'Foo_2' function. V2589. The functions from time.h/ctime should not be used. The 'ThreadStatic' attribute is applied to a non-static 'A' field and will be ignored. A pattern was detected: A || (A && ). MISRA. V3107. It is possible that macro expansion resulted in incorrect evaluation order. The expression contains a suspicious mix of integer and real types. Youll need to comment out this line of code in order to make your code compile. V660. By clicking Sign up for GitHub, you agree to our terms of service and V2005. V014. The code's operational logic does not correspond with its formatting. MISRA. Passing cheap-to-copy argument by reference may lead to decreased performance. Not all IDisposable members are properly disposed. V563. The loop counter should not have floating-point type. The use of 'if (A) {} else if (A) {}' pattern was detected. Implicit type conversion N argument of function 'foo' to memsize type. This is unexpected behavior. V3144. Object should not be assigned or copied to an overlapping object. MISRA. There is an easy solution to the problem, even if we understand that every condition is covered we should add a return statement at the end of the function so the compiler is sure that the non-void function will be returning some value. Suspicious declaration. Unsafe usage of the 'bool' and integer types together in the operation '&='. An example of data being processed may be a unique identifier stored in a cookie. V690. (i have tried it with just else instead of else if and get same error). V6043. Only values returned from fgetpos() can be used as arguments to fsetpos(). Identical expression to the left and to the right of compound assignment. The argument's value is greater than the size of the collection. Possible LDAP injection. V631. Decreased performance. Attempt to free memory containing the 'int A[10]' array by using the 'free(A)' function. Variable with static storage duration is declared inside the inline function with external linkage. V742. MISRA. OWASP. V560. However, in modern programming they are more accepted, particularly when they can be used to make a function simpler, or are used to abort a function early due to some error condition. V3133. Giving short names to global variables is considered to be bad practice. Consider inspecting the expression. V595. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value. Consider inspecting the expression. Subtraction, >, >=, <, <= should be applied only to pointers that address elements of the same array. Unary minus operator does not modify a bool type value. It is possible that an error is present. If you do this, the last statement before End Function should be a Return statement. Consider assigning event to a local variable before invoking it. Consider checking for misprints. Three potential reasons for issue the warning (elevated to an error) in spite of this come to mind: Due to the way the compiler is constructed, warnings are generally reported early, and suppressing this warning based on later analysis would be difficult. Not the answer you're looking for? V2567. Consider using '||' and '&&' instead. V670. The 'delete' operator is applied to non-pointer. Value is subtracted from unsigned variable. The 'Foo' function is called twice in the specified expression to calculate length of the same string. It is suspicious that the assignment operator takes an object by a non-constant reference and returns this object. This can result in an overflow. Pointer to an object of the class is cast to unrelated class. A write outside the bounds of this variable may occur. V124. V6079. As the diagnostic message states, the function does have a control path where a value isn't returned. For more information, see "Behavior" in Function Statement. No return statement is required. So, the compiler generates an error. V2533. V641. It is possible that different variables are used inside initializer and iterator. AUTOSAR. The resulting value may be inaccurate. Exception caught by handler for base class. The warnings you describe only occur if you do not leave the scope, but let the control flow reach its end without returning a value. From the documentation of JSON_THROW_USER: Note that JSON_THROW_USER should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield undefined behavior. Variables are initialized through the call to the same function. The expression is incorrect or can be simplified. Value of the expression should not be converted to the different essential type or the narrower essential type. V540. Signed integer overflow in arithmetic expression. Potentially tainted data is used to create query. The compiler isn't going to go to very much trouble to detect this situation, because functions like throw_blah which are guaranteed to never return are rare, and because except in the simplest of situations, there's no way for it to reliably do so. What's the cheapest way to buy out a sibling's share of our parents house if I have no cash and want to pay less than the appraised value? Possible server-side request forgery. Appending new suppressed messages to it is not possible. Can you still use Commanders Strike if the only attack available to forego is an attack against an ally? V5302. V676. V820. V3073. Priority of '+' operation is higher than priority of '<<' operation. Code contains invisible characters that may alter its logic. Unity Engine. V661. The pointer is cast to an integer type of a larger size. It is possible that a typo is present inside the expression. V1076. Did the drapes in old theatres actually say "ASBESTOS" on them? It is more efficient to search for 'X' character rather than a string. The operator '||' operator is surrounded by opposite expressions 'x' and '!x'. V781. V507. Two or more case-branches perform the same actions. Possibility of decreased performance. MISRA. Automatic unboxing of a variable may cause NullPointerException. The other function parameter expects a file path instead. One of the operands in the operation equals NN. Connect and share knowledge within a single location that is structured and easy to search. Decreased performance. V005. Check for typos and consider using the 'default:' operator instead. Probably the '!='/'-='/'+=' should be used here. OWASP. It demonstrates the return statement, and how it's used both to end function execution, and optionally, to return a value. V3001. Potentially tainted data is used in the XPath expression. V6075. Why are players required to record the moves in World Championship Classical games? V3040. V3502. AUTOSAR. V2504. Conditional expressions of 'if' statements located next to each other are identical. OWASP. Consider inspecting the loop expression. Particularly, if during the function execution an exception is thrown and is not caught in the body of the same function, there will be no undefined behavior. V3163. V2010. Possible log injection. V6092. A terminal null is present inside a string. AUTOSAR. V6068. V6085. No more than one iteration of the loop will be performed. V301. The version of your suppress file is outdated. Significant bits may be lost. Potential logical error. MISRA. Find centralized, trusted content and collaborate around the technologies you use most. Implementation of 'compareTo' overloads the method from a base class. V621. V6004. Loop may execute incorrectly or may not execute at all. Use of jump statements in 'finally' block can lead to the loss of unhandled exceptions. V699. Error on missing return statement under GCC. V5607. AUTOSAR. Consider synchronizing the field on all usages. V5622. V511. WPF: writing and reading are performed on a different Dependency Properties. V1060. See documentation for details. If total energies differ across different software, how do I decide which software to use? It is highly probable that the semicolon ';' is missing after 'return' keyword. V202. V3095. V6041. V752. The 'value' parameter is rewritten inside a property setter, and is not used after that. V1064. OWASP. V6076. Object is used as an argument to its own method. This file is marked with copyleft license, which requires you to open the derived source code. V731. Values of different enum types are compared. Wrong variable is probably used in the for operator as an index. Consider inspecting the expression. The '\0xNN' characters were encountered. V3135. V002. V763. We must also say what type of enter the function lives returning, e.g. Pointer to local array 'X' is stored outside the scope of this array. V3153. V6100. Unbounded functions performing string operations should not be used. V102. An unconditional 'break/continue/return/goto' within a loop. What is scrcpy OTG mode and how does it work? The 'swap' function may interchange a variable with itself. But, do are you sure you want your return statement inside your loop to begin with? Code formatting implies that the statement should not be a part of the 'then' branch that belongs to the preceding 'if' statement. Possible XSS vulnerability. To compile the example, create a source code file named C_return_statement.c. As report_square takes no parameters and returns void, we don't assign its result to a variable. V2593. privacy statement. MISRA. V671. V303. V688. V013. The 'if (ptr != NULL)' check can be removed. V108. The use of 'if (A) {} else if (A) {}' pattern was detected. The 'sizeof' expression returns the size of the container type, not the number of elements. Making statements based on opinion; back them up with references or personal experience. V3140. In a main function, the return statement and expression are optional. Uninitialized variables are used when initializing the 'A' variable. V784. V682. V5624. But below is not the case so why does it get compile, is there something else expected by Oracle. Value of a variable is checked after it is used. Possible meaningless check for null, as memory was allocated using 'new' operator. Consider replacing standard container with a different one. Otherwise, the integer division operator would be used, and the fractional part would be lost. Array size should be specified explicitly when array declaration uses designated initialization. OWASP. How to force Mathematica to return `NumericQ` as True when aplied to some variable in Mathematica? V544. V1028. Here's the correct version: The 'main' and 'wmain' functions are the exceptions. Both operands of the '??' Condition of a loop is always true/false. V6033. Potentially negative value is used as the size of an array. Consider inspecting the 'foo' function. Consider replacing the expression 'AA' with 'BB'. Value of a composite expression should not be cast to a different essential type category or a wider essential type. A Function procedure has at least one possible path through its code that does not return a value. A 'wchar_t *' type string is incorrectly converted to 'BSTR' type string. Function printHi has a void return type, meaning it doesnt return a value. V3013. WPF: the type registered for DependencyProperty does not correspond with the type of the property used to access it. operator instead. V1080. Consider checking the Nth actual argument of the 'Foo' function. Possible incorrect order of arguments passed to method.
