syspath_once

Controls how include files are treated when #pragma once is enabled.

Syntax

#pragma syspath_once on | off | reset

Targets
All platforms.
Remarks

If you enable this pragma, files called in #include <> and #include "" directives are treated as distinct, even if they refer to the same file.

This pragma does not correspond to any panel setting. To check this setting, use __option (syspath_once), described in Checking Settings. The default setting is on.
