MONGOC_GRIDFS_FIND_ONE(3) libmongoc MONGOC_GRIDFS_FIND_ONE(3) WARNING: Deprecated since version 1.5.0: This function is deprecated, use mongoc_gridfs_find_one_with_opts() instead. SYNOPSIS mongoc_gridfs_file_t * mongoc_gridfs_find_one (mongoc_gridfs_t *gridfs, const bson_t *query, bson_error_t *error); PARAMETERS • gridfs: A mongoc_gridfs_t. • query: A bson_t. • error: An optional location for a bson_error_t or NULL. DESCRIPTION This function shall execute a query on the underlying gridfs implemen- tation. The first file matching query will be returned. If there is an error, NULL is returned and error is filled out; if there is no error but no matching file is found, NULL is returned and the error code and domain are 0. This function is considered a retryable read operation. Upon a tran- sient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If retryreads is false in the URI (see mongoc_uri_t) the retry behavior does not apply. ERRORS Errors are propagated via the error parameter. RETURNS A newly allocated mongoc_gridfs_file_t or NULL if no file could be found. You must free the resulting file with mongoc_gridfs_file_destroy() if non-NULL.
