|KLDUNLOAD(2)||FreeBSD System Calls Manual||KLDUNLOAD(2)|
NAMEkldunload, kldunloadf — unload kld files
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include < sys/param.h>
#include < sys/linker.h>
kldunload( int fileid);
kldunloadf( int fileid, int flags);
DESCRIPTIONThe 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 VALUESUpon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORSThe 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.
