LIBRARY


.Lb libc

SYNOPSIS


.In sys/param.h
.In sys/linker.h int kldunload int fileid int kldunloadf int fileid int flags

DESCRIPTION

The kldunload system call unloads a kld file from the kernel that was previously linked via kldload(2).

The kldunloadf system call accepts an additional flags argument, which may be one of LINKER_UNLOAD_NORMAL, giving the same behavior as kldunload, or LINKER_UNLOAD_FORCE, which causes the unload to ignore a failure to quiesce the module.

RETURN VALUES


.Rv -std

ERRORS

The file referred to by fileid is unloaded unless:
[EPERM]
  You do not have access to unlink the file from the kernel.
[ENOENT]
  The file was not found.
[EBUSY]
  You attempted to unload a file linked by the kernel.
[EINVAL]
  The kldunloadf system call was passed invalid flags.
