mongoc_collection_find_and_modify_with_opts()

Synopsis

bool
mongoc_collection_find_and_modify_with_opts (
   mongoc_collection_t *collection,
   const bson_t *query,
   const mongoc_find_and_modify_opts_t *opts,
   bson_t *reply,
   bson_error_t *error);

Parameters

• collection: A mongoc_collection_t.

• query: A bson_t containing the query to locate target document(s).

• opts: A find and modify options. Must not be NULL.

• reply: A maybe-NULL pointer to overwritable storage for a bson_t to contain the results.

• error: An optional location for a bson_error_t or NULL.

Description

Update and return an object.

reply is always initialized, and must be freed with bson_destroy().

If an unacknowledged write concern is set (through mongoc_find_and_modify_opts_append()), the output reply is always an empty document.

On success, the output reply contains the full server reply to the findAndModify command. See the MongoDB Manual page for findAndModify for the expected server reply.

Errors

Errors are propagated via the error parameter.

Returns

Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error.

A write concern timeout or write concern error is considered a failure.

Example

See the example code for mongoc_find_and_modify_opts_t.
