W8081: Void functions may not return a value
Example
Collapse All

(Command-line option to suppress warning: -w-voi) 

Your source file declared the current function as returning void, but the compiler encountered a return statement with a value. The value of the return statement will be ignored. 

 

Example
Copy Code
// This HAS to be in a "C" file.  In a "C++" file this would be an error

 

Copy Code
void foo()

 

Copy Code
{

 

Copy Code
        return 0;       // Can't return a value from a void function

 

Copy Code
}
