Overview
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 EEXIST (signifying that the requested module was already loaded).
