MODNEXT(2)						      BSD System Calls Manual							MODNEXT(2)

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).
