mongoc_collection_command()

Synopsis

mongoc_cursor_t *
mongoc_collection_command (mongoc_collection_t       *collection,
                           mongoc_query_flags_t       flags,
                           uint32_t                   skip,
                           uint32_t                   limit,
                           uint32_t                   batch_size,
                           const bson_t              *command,
                           const bson_t              *fields,
                           const mongoc_read_prefs_t *read_prefs)
BSON_GNUC_WARN_UNUSED_RESULT;

This function creates a cursor which will execute the command when mongoc_cursor_next is called on it. The collection's read preference, read concern, and write concern are not applied to the command, and mongoc_cursor_next will not check the server response for a write concern error or write concern timeout.

Parameters

collection	A mongoc_collection_t.
flags	A mongoc_query_flags_t.
skip	A uint32_t with the number of documents to skip or zero.
limit	A uint32_t with the max number of documents to return or zero.
batch_size	A uint32_t with the number of documents in each batch or zero. Default is 100.
command	A bson_t containing the command to execute.
fields	A bson_t containing the fields to return or NULL. Not all commands support this option.
read_prefs	An optional mongoc_read_prefs_t. Otherwise, the command uses mode MONGOC_READ_PRIMARY.

Returns

A mongoc_cursor_t.

The cursor should be freed with mongoc_cursor_destroy().
