Name
       prof - profile within a function

Syntax
       #define MARK
       #include <prof.h>

       void MARK (name)

Description
       The  symbol  produces  a mark called name that is treated the same as a function entry point.  Execution of the mark increments the counter
       for that mark, and the program-counter time spent is accounted to the preceding mark or to the function if a preceding mark is  not  within
       the active function.

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

       For marks to be effective, the symbol must be defined before the header file is included.  This may be defined by a preprocessor  directive
       as in the synopsis, or by a command line argument.  For example:
       cc -p -DMARK foo.c
       If is not defined, the statements may remain in the source files, but they will be ignored.

Examples
       In  the following example, marks are used to determine how much time is spent in each loop.  Unless the example is compiled with defined on
       the command line, the marks are ignored:
       #include <prof.h>
       foo( )
       {
	    int i, j;
	    .
	    .
	    .
	    MARK(loop1);
	    for (i = 0; i < 2000; i++) {
		 . . .
	    }
	    MARK(loop2);
	    for (j = 0; j < 2000; j++) {
		 . . .
	    }
       }

       displayed.

OPTIONS

       -p, --printer=printer
	      Select a printer:
		flat - Prints a flat profile as text (default).
		graph - Prints a graph profile as text.
		graph_html - Prints a graph profile as html.
		call_tree - format for KCacheGrind

       -m, --min_percent=min_percent
	      The minimum percent a method must take before being included in output reports.  This option is not supported for call tree.

       -f, --file=path
	      Output results to a file instead of standard out.

       --mode=measure_mode
	      Select what ruby-prof should measure
		process - Use process time (default).
		wall - Use wall time.
		cpu - Use the CPU clock counter (only supported on Pentium and PowerPCs).

       --replace-progname
	      Replace $0 when loading the ruby source file.

       -h, --help
