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  implementation.  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 transient 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.
