\fBWARNING:\fP
.INDENT 0.0
.INDENT 3.5
Deprecated since version 1.11.0: This function is deprecated and should not be used in new code.
.sp
Please use \fI\%mongoc_cursor_new_from_command_reply_with_opts()\fP in new code.
.sp
When migrating from the deprecated \fI\%mongoc_cursor_new_from_command_reply()\fP to \fI\%mongoc_cursor_new_from_command_reply_with_opts()\fP,
note that options previously passed to the \fBreply\fP argument (e.g. \(dqbatchSize\(dq) must instead be provided in the \fBopts\fP argument.

.SH PARAMETERS
.INDENT 0.0
.IP \(bu 2
\fBclient\fP: A \fI\%mongoc_client_t\fP\&.
.IP \(bu 2
\fBreply\fP: The reply to a command, such as \(dqaggregate\(dq, \(dqfind\(dq, or \(dqlistCollections\(dq, that returns a cursor document. The reply is destroyed by \fBmongoc_cursor_new_from_command_reply\fP and must not be accessed afterward.
.IP \(bu 2
\fBserver_id\fP: The opaque id of the server used to execute the command.
.UNINDENT
.SH DESCRIPTION
.sp
Some MongoDB commands return a \(dqcursor\(dq document. For example, given an \(dqaggregate\(dq command:
.INDENT 0.0
.INDENT 3.5
.sp
.EX
{ \(dqaggregate\(dq : \(dqcollection\(dq, \(dqpipeline\(dq : [], \(dqcursor\(dq : {}}
.EE

.sp
The server replies:

.EX
{
   \(dqcursor\(dq : {
      \(dqid\(dq : 1234,
      \(dqns\(dq : \(dqdb.collection\(dq,
      \(dqfirstBatch\(dq : [ ]
   },
   \(dqok\(dq : 1
}

\fBmongoc_cursor_new_from_command_reply\fP is a low\-level function that initializes a \fI\%mongoc_cursor_t\fP from such a reply. Additional options such as \(dqtailable\(dq or \(dqawaitData\(dq can be included in the reply.
.sp
When synthesizing a completed cursor response that has no more batches (i.e. with cursor id 0), \fBserver_id\fP may be 0. If the cursor response is not completed (i.e. with non\-zero cursor id), pass the \fBserver_id\fP of the server used to create the cursor.
.sp
Use this function only for building a language driver that wraps the C Driver. When writing applications in C, higher\-level functions such as \fI\%mongoc_collection_aggregate()\fP are more appropriate, and ensure compatibility with a range of MongoDB versions.
.SH RETURNS
.sp
A \fI\%mongoc_cursor_t\fP\&. On failure, the cursor\(aqs error is set. Check for failure with \fI\%mongoc_cursor_error()\fP\&.
