NAME
       prof - profile within a function

SYNOPSIS
       #define MARK
       #include <prof.h>

       void MARK(name);

DESCRIPTION
       MARK  introduces a mark called name that is treated the same as a func‐
       tion entry point. Execution of the mark adds  to  a  counter  for  that
       mark,  and  program-counter  time spent is accounted to the immediately
       preceding mark or to the function  if  there  are  no  preceding  marks
       within the active function.


       name  may  be any combination of letters, numbers, or underscores. Each
       name in a single compilation must be unique, but may be the same as any
       ordinary program symbol.


       For  marks  to be effective, the symbol MARK must be defined before the
       header prof.h is included, either by a preprocessor directive as in the
       synopsis, or by a command line argument:


       cc-p -DMARK work.c


       If  MARK  is  not defined, the MARK(name) statements may be left in the
       source files containing them and are ignored. prof -g must be  used  to
       get information on all labels.

EXAMPLES
       In  this example, marks can be used to determine how much time is spent
       in each loop. Unless this example is compiled with MARK defined on  the
       command line, the marks are ignored.

         #include <prof.h>
         work( )
         {
                 int i, j;
                 . . .
                 MARK(loop1);
                 for (i = 0; i < 2000; i++) {
                         . . .
                 }
                 MARK(loop2);
                 for (j = 0; j < 2000; j++) {
                         . . .
                 }
         }

NOTES
       The  MARK()  facility is obsolete and may be removed in future releases
       of Oracle Solaris.
