* _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

|
|
* 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.
