MISRA C:2012  Rule-15.5:  (Advisory)			A function should have a single point of exit at the end

Amplification:

A function should have no more than one return statement.

When a return statement is used, it should be the final statement in the compound statement that forms the body of the function.

Example Code:

#include "misra.h"
#include "m3cmex.h"


extern int16_t rule_1505( void )                                /* 2889 */
{
   if ( s16a > 0 )
   {
      return 0;
   }
   else
   {
      return 1;
   }
}

QAC messages that encompass this guideline:

2889	This function has more than one 'return' path.
