Overview

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

Return values

The kldunload() function returns the value 0 if successful; 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.
