# modfnext(2freebsd)

return the modid of the next kernel module

## 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).
