The function
|
|
.Fn modnext
|
|
returns the modid of the next kernel module (that is, the one after

|
|
is the last module in the list.
|
|
.Pp

If the
|
|
.Va modid
|
|
value is 0, then
|
|
.Fn modnext
|
|
will return the modid of the first module.
|
|
.Fn modfnext
|
|
must always be given a valid modid.
|
|
.Sh RETURN VALUES
|
|
.Fn modnext
|
|
returns the modid of the next module (see DESCRIPTION) or 0. If an error
|
|

|
.Sh ERRORS
|
|
The only error set by
|
|
.Fn modnext
|
|
is
|
|
