NAME
kldunload -- unload a file from the kernel SYNOPSIS
kldunload [-fv] -i id ... kldunload [-fv] [-n] name ... DESCRIPTION
The kldunload utility unloads a file which was previously loaded with kldload(8). The following options are available: -f Force the unload. This ignores error returns to MOD_QUIESCE from the module and implies that the module should be unloaded even if it is currently in use. The users are left to cope as best they can. -v Be more verbose. -i id Unload the file with this ID. -n name Unload the file with this name. name Unload the file with this name. EXIT STATUS
The kldunload utility exits 0 on success, and >0 if an error occurs. SEE ALSO
kldunload(2), kldload(8), kldstat(8) HISTORY
The kldunload utility first appeared in FreeBSD 3.0, replacing the lkm interface. AUTHORS

KLDUNLOAD(2)						      BSD System Calls Manual						      KLDUNLOAD(2)

NAME
kldunload, kldunloadf -- unload kld files LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/param.h> #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: [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. SEE ALSO
