NAME

     kldload --- load KLD files into the kernel

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/param.h>
     #include <sys/linker.h>

     int
     kldload(const char *file);

DESCRIPTION

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

RETURN VALUES

     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.

ERRORS

     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.
