.SH "DESCRIPTION"
.PP
Load a module using the user mode module loader\&. The function returns zero on success or a negative errno code or positive exit code from
\(lqmodprobe\(rq
on failure\&. Note that a successful module load does not mean the module did not then unload and exit on an error of its own\&. Callers must check that the service they requested is now available not blindly invoke it\&.
.PP
If module auto\-loading support is disabled then this function becomes a no\-operation\&.
