MONGOC_CURSOR_NEW_FROM_COMMAND_REPLY_WITH_OPTS

NAME

mongoc_cursor_new_from_command_reply_with_opts - mongoc_cursor_new_from_command_reply_with_opts()

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.

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().
