  • 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.

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.

Errors are propagated via the error parameter.

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.
