.In libutil.h
|

.Fn kld_isloaded "const char *name"

|
|
.Sh DESCRIPTION
|
|
These functions facilitate loading kernel modules from userland
|
|
applications.
|
|
.Pp
|
|
The
|
|
.Fn 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
|
|
.Pq Pa cpufreq.ko ,
|
|
the same name without the
|
|
.Pa .ko
|
|
extension
|
|
.Pq Pa cpufreq ,
|
|
or the name of a module contained within that file
|
|
.Pq Pa cpu/ichss .
|
|
Only the latter will return correct results if the module is compiled
|
|
into the kernel.
|
|
.Pp
|
|
The
|
|
.Fn kld_load
|
|
function is a simple wrapper around the
|
|
.Xr kldload 2
|
|
function.
|
|
It returns zero if and only if the corresponding
|
|
.Fn kldload
|
|
call succeeded or returned
|
|
.Er EEXIST
|
|
(signifying that the requested module was already loaded).
