QA·C Help - 0428

	0428	Function identifier is not followed by () but a function call may be intended.

Functions		REFERENCE - ISO:C90-6.2.2.1 Lvalues and Function Designators

A function identifier is being used without parentheses and it therefore represents a constant pointer value (the address of the function), rather than a call to the function.

In this particular context a constant pointer value does not make sense. Other messages will probably be generated including message 3635.

For example:


/*PRQA S 3408,3447 ++*/

extern int foo( void );

extern void func( void )
{
    foo;                        /* Message 0428 + 3635 + 3112 - no side effects */

    if (foo)                    /* Message 0428 + 3635 + 3344 */
    {
    }

}
