Function notmuch_sys::notmuch_message_get_message_id [−] [src]

pub unsafe extern "C" fn notmuch_message_get_message_id(
    message: *mut notmuch_message_t
) -> *const c_char

Get the message ID of 'message'.

The returned string belongs to 'message' and as such, should not be modified by the caller and will only be valid for as long as the message is valid, (which is until the query from which it derived is destroyed).

This function will not return NULL since Notmuch ensures that every message has a unique message ID, (Notmuch will generate an ID for a message if the original file does not contain one).
