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).

     modstat(2), kld(4)

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