MISRA-C:2004  Rule  16.9:  (Required)			A function identifier shall only be used with either a preceding &, or with a parenthesised parameter list, which may be empty.

if ( f )    /* not compliant - gives a constant non-zero value which is
  {            the address of f - use either f() or &f                  */
    /* ... */
}

then it is not clear if the intent is to test if the address of the function is not NULL or that a call to the function f() should be made.

QAC messages that encompass this guideline:

3635	Function identifier used as a pointer without a preceding & operator.
