-.SH DESCRIPTION
-This routine provides a means to find out in what areas your program
-spends most of its time.
-The argument
-.I buf
-points to
-.I bufsiz
-bytes of core.
-Every virtual 10 milliseconds, the user's program counter (PC)
-is examined:
-.I offset
-is subtracted and the result is multiplied by
-.I scale
-and divided by 65536.
-If the resulting value is less than
-.IR bufsiz ,
-then the corresponding entry in
-.I buf
-is incremented.
-If
-.I buf
-is NULL, profiling is disabled.
-.SH RETURN VALUE
-Zero is always returned.

-.SH HISTORY
-Similar to a call in SVr4.
-.SH BUGS
-.BR profil ()
-cannot be used on a program that also uses
-.B ITIMER_PROF
-interval timers (see
-.BR setitimer (2)).
-.P
-True kernel profiling provides more accurate results.
-.\" Libc 4.4 contained a kernel patch providing a system call profil.
