From d21e4eb8ae10d704a01cfd0278f4efd636842457 Mon Sep 17 00:00:00 2001 From: Yang Tse Date: Thu, 15 Feb 2007 16:23:24 +0000 Subject: introduce uppercase macros SOCKERRNO, SET_SOCKERRNO(), ERRNO and SET_ERRNO() making them available to any source code file which includes "setup.h". Macro SOCKERRNO / SET_SOCKERRNO() returns / sets the *socket-related* errno (or equivalent) on this platform to hide platform details to code using it. Macro ERRNO / SET_ERRNO() returns / sets the NOT *socket-related* errno (or equivalent) on this platform to hide platform details to code using it. --- ares/setup_once.h | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'ares') diff --git a/ares/setup_once.h b/ares/setup_once.h index 202b0cadc..25eacf51e 100644 --- a/ares/setup_once.h +++ b/ares/setup_once.h @@ -158,5 +158,33 @@ typedef int sig_atomic_t; #endif +/* + * Macro SOCKERRNO / SET_SOCKERRNO() returns / sets the *socket-related* errno + * (or equivalent) on this platform to hide platform details to code using it. + */ + +#ifdef USE_WINSOCK +#define SOCKERRNO ((int)WSAGetLastError()) +#define SET_SOCKERRNO(x) (WSASetLastError((int)(x))) +#else +#define SOCKERRNO (errno) +#define SET_SOCKERRNO(x) (errno = (x)) +#endif + + +/* + * Macro ERRNO / SET_ERRNO() returns / sets the NOT *socket-related* errno + * (or equivalent) on this platform to hide platform details to code using it. + */ + +#ifdef WIN32 +#define ERRNO ((int)GetLastError()) +#define SET_ERRNO(x) (SetLastError((DWORD)(x))) +#else +#define ERRNO (errno) +#define SET_ERRNO(x) (errno = (x)) +#endif + + #endif /* __SETUP_ONCE_H */ -- cgit v1.2.3
