notmuch_sys::notmuch_filenames_get

pub unsafe extern fn notmuch_filenames_get(filenames: *mut notmuch_filenames_t) -> *const c_char

Get the current filename from 'filenames' as a string.

Note: The returned string belongs to 'filenames' and has a lifetime identical to it (and the directory to which it ultimately belongs).

It is acceptable to pass NULL for 'filenames', in which case this function will always return NULL.
