KLD(3)		       FreeBSD Library Functions Manual			KLD(3)

NAME
     kld_isloaded, kld_load -- kld utility functions

LIBRARY
     System Utilities Library (libutil,	-lutil)

SYNOPSIS
     #include <libutil.h>

     int
     kld_isloaded(const	char *name);

     int
     kld_load(const char *name);

DESCRIPTION
     These functions facilitate	loading	kernel modules from userland applica-
     tions.

     The kld_isloaded()	function takes a name and returns a non-zero value if
     a module of that name is currently	loaded.	 The name can be either	the
     name of a module file (cpufreq.ko), the same name without the .ko exten-
     sion (cpufreq), or	the name of a module contained within that file
     (cpu/ichss).  Only	the latter will	return correct results if the module
     is	compiled into the kernel.

     The kld_load() function is	a simple wrapper around	the kldload(2) func-
     tion.  It returns zero if and only	if the corresponding kldload() call
     succeeded or returned EEXIST (signifying that the requested module	was
     already loaded).

HISTORY
     The kld_isloaded()	and kld_load() functions first appeared	in
     FreeBSD 6.3.

AUTHORS
     The kld_isloaded()	and kld_load() functions and this manual page were
     written by	Dag-Erling Smorgrav <des@FreeBSD.org>.
