SYNOPSIS
mongoc_cursor_t * mongoc_cursor_new_from_command_reply_with_opts (mongoc_client_t *client, bson_t *reply, const bson_t *opts);
PARAMETERS
• client: A mongoc_client_t. • reply: The reply to a command, such as "aggregate", "find", or "listCollections", that returns a cursor document. The reply is destroyed by mongoc_cursor_new_from_command_reply_with_opts and must not be accessed afterward. • opts: A bson_t. opts may be NULL or a BSON document with additional options, which have the same meaning for this function as for mongoc_collection_find_with_opts(): • awaitData • batchSize • limit • maxAwaitTimeMS • serverId • sessionId • skip • tailable
DESCRIPTION
Some MongoDB commands return a "cursor" document. For example, given an "aggregate" command: { "aggregate" : "collection", "pipeline" : [], "cursor" : {}} The server replies: { "cursor" : { "id" : 1234, "ns" : "db.collection", "firstBatch" : [ ] }, "ok" : 1 } mongoc_cursor_new_from_command_reply_with_opts is a low-level function that initializes a mongoc_cursor_t from such a reply. When synthesizing a completed cursor response that has no more batches (i.e. with cursor id 0), serverId may be 0. If the cursor response is not completed (i.e. with non-zero cursor id), pass the serverId of the server used to create the cursor. Use this function only for building a language driver that wraps the C Driver. When writing applications in C, higher-level functions such as mongoc_collection_aggregate() are more appropriate, and ensure compatibility with a range of MongoDB versions.
RETURNS
A mongoc_cursor_t. On failure, the cursor's error is set. Check for failure with mongoc_cursor_error().
