NAME

modnext — return the modid of the next kernel module

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <sys/param.h>
#include <sys/module.h>

int
modnext(int modid);

int
modfnext(int modid);

DESCRIPTION

The modnext() system call returns the modid of the next kernel module (that is, the one after modid) or 0 if modid is the last module in the list.

If the modid value is 0, then modnext() will return the modid of the first module. The modfnext() system call must always be given a valid modid.

RETURN VALUES

The modnext() system call returns the modid of the next module (see DESCRIPTION) or 0. If an error occurs, errno is set to indicate the error.

ERRORS

The only error set by modnext() is ENOENT, which is set when modid refers to a kernel module that does not exist (is not loaded).
