INTERFACE Cerrno;

FROM Ctypes IMPORT int;

 We cannot access errno directly as a variable, because on some systems
   it is a C macro that expands to something more complicated.


   The errno value is preserved across thread switches. 


<*EXTERNAL "Cerrno__GetErrno"*>
PROCEDURE GetErrno(): int;

<*EXTERNAL "Cerrno__SetErrno"*>
PROCEDURE SetErrno(e: int);

END Cerrno.
