MONGOC_GRIDFS_...NE_BY_FILENAME(3) libmongocMONGOC_GRIDFS_...NE_BY_FILENAME(3) SYNOPSIS mongoc_gridfs_file_t * mongoc_gridfs_find_one_by_filename (mongoc_gridfs_t *gridfs, const char *filename, bson_error_t *error); PARAMETERS • gridfs: A mongoc_gridfs_t. • filename: A UTF-8 encoded string containing the filename. • error: An optional location for a bson_error_t or NULL. DESCRIPTION Finds the first file matching the filename specified. 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 Returns a newly allocated mongoc_gridfs_file_t if successful. You must free the resulting file with mongoc_gridfs_file_destroy() when no longer in use.
