returns the modid of the next kernel module (that is, the one after
.Va modid )
or 0 if

must always be given a valid modid.
.Sh RETURN VALUES

If an error
occurs,
.Va errno
is set to indicate the error.
.Sh ERRORS
The only error set by
.Fn modnext
is
.Er ENOENT ,
which is set when
.Va modid
refers to a kernel module that does not exist (is not loaded).
