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 kldunload(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.
