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 applications.

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 extension (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) function. It returns zero if and only if the corresponding kldload ();
call succeeded or returned Er EEXIST (signifying that the requested module was already loaded).
