* _ cairo_error :
* @ status : a status value indicating an error , ( eg . not
* % CAIRO_STATUS_SUCCESS )
*
* Checks that status is an error status , but does nothing else .
*
* All assignments of an error status to any user - visible object
* within the cairo application should result in a call to
* _ cairo_error ( ) .
*
* The purpose of this function is to allow the user to set a
* breakpoint in _ cairo_error ( ) to generate a stack trace for when the
* user causes cairo to detect an error .
*
* Return value : the error status .
