LIBRARY

SYNOPSIS
#include <sys/param.h>
#include <sys/linker.h>
int
kldunload(int fileid);
DESCRIPTION
The kldunload() system call unloads a kld file from the kernel that was
previously linked via kldload(2).
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the
value -1 is returned and the global variable errno is set to indicate the
error.
ERRORS
The file referred to by fileid is unloaded unless:
[EPERM] You don't have access to unlink the file from the ker-
nel.
[ENOENT] The file was not found.
[EBUSY] You attempted to unload a file linked by the kernel.
