Function notmuch_sys::notmuch_filenames_move_to_next

pub unsafe extern "C" fn notmuch_filenames_move_to_next(
    filenames: *mut notmuch_filenames_t
)

Move the 'filenames' iterator to the next filename.

If 'filenames' is already pointing at the last filename then the iterator will be moved to a point just beyond that last filename, (where notmuch_filenames_valid will return FALSE and notmuch_filenames_get will return NULL).

It is acceptable to pass NULL for 'filenames', in which case this function will do nothing.
