profil - Tru64 UNIX specific behavior (CrCh2)

Problem description

Some Tru64 UNIX specific behavior is not supported in the profil function on HP-UX.

The profil function starts and stops execution profiling. The format is:

void profil(  unsigned short *short_buffer,
                  unsigned int buffer_size,
                  void  *offset, 
                  unsigned int scale );

In Tru64 UNIX, if the offset is -1, the first argument becomes struct profil_args *args, indicating that multiple discontiguous address ranges are to be profiled. HP-UX does not support this concept.
