|KLDUNLOAD(2)||System Calls Manual||KLDUNLOAD(2)|
NAME¶kldunload, kldunloadf — unload kld files
LIBRARY¶Standard C Library (libc, -lc)
#include <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¶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:
- You do not have access to unlink the file from the kernel.
- The file was not found.
- You attempted to unload a file linked by the kernel.
- The kldunloadf() system call was passed invalid flags.

HISTORY¶The kld interface first appeared in FreeBSD 3.0.
