kldload – load KLD files into the kernel

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO HISTORY

Standard C Library (libc, -lc)

#include <sys/param.h>

#include <sys/linker.h>

int
kldload(const char *file);

The kldload() system call loads a kld file into the kernel using the kernel linker.

The kldload() system call returns the fileid of the kld file which was loaded into the kernel. If an error occurs, kldload() will return -1 and set errno to indicate the error.

The named file is loaded unless:

[EPERM]
	You do not have access to read the file or link it with the kernel. You should be the root user to be able to use the kld system calls.
[EFAULT]
	Bad address encountered when adding kld info into the kernel space.
[ENOMEM]
	There is no memory to load the file into the kernel.
[ENOENT]
	The file was not found.
[ENOEXEC]
	The file format of file was unrecognized.
[EEXIST]
	The supplied file has already been loaded.

The kld interface first appeared in FreeBSD 3.0 .
