SYNOPSIS

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

DESCRIPTION

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

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

RETURN VALUES

Rv -std

Bq Er ENOENT: The file was not found.
Bq Er EBUSY: You attempted to unload a file linked by the kernel.
Bq Er EINVAL: The Fn kldunloadf system call was passed invalid flags.
