NAME

6       mongoc_change_stream_next - mongoc_change_stream_next()
7

SYNOPSIS

9          bool
10          mongoc_change_stream_next (mongoc_change_stream_t *stream,
11                                     const bson_t **bson);
12
13       This  function iterates the underlying cursor, setting bson to the next
14       document. This will block for a maximum of maxAwaitTimeMS  milliseconds
15       as  specified  in  the  options when created, or the default timeout if
16       omitted. Data may be  returned  before  the  timeout.  If  no  data  is
17       returned this function returns false.
18

PARAMETERS

20       · stream: A mongoc_change_stream_t.
21
22       · bson: The location for the resulting document.
23

RETURNS

25       This  function  returns true if a valid bson document was read from the
26       stream.  Otherwise, false if there was an  error  or  no  document  was
27       available.
28
29       Errors  can  be determined with the mongoc_change_stream_error_document
30       function.
31

LIFECYCLE

33       Similar to mongoc_cursor_next the lifetime of bson is  until  the  next
34       call  to  mongoc_change_stream_next, so it needs to be copied to extend
35       the lifetime.
