/**
 * _cairo_region_set_error:
 * @region: a region
 * @status: a status value indicating an error
 *
 * Atomically sets region->status to @status and calls _cairo_error;
 * Does nothing if status is %CAIRO_STATUS_SUCCESS or any of the internal
 * status values.
 *
 * All assignments of an error status to region->status should happen
 * through _cairo_region_set_error(). Note that due to the nature of
 * the atomic operation, it is not safe to call this function on the
 * nil objects.
 *
 * 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.
