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 function 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 up to six 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 file <prof.h> is included. This may be defined by a preprocessor directive as in the synopsis, or by a command line argument, such as:

cc -p -DMARK foo.c

If MARK is not defined, the MARK (name) statements may be left in the source files containing them and will be ignored.

EXAMPLE

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