From fea72cc0336f4d90875cdddc1aa9739dcbb174f5 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Thu, 3 Sep 2015 13:22:51 +0200 Subject: macro: introduce new PID_TO_PTR macros and make use of them This adds a new PID_TO_PTR() macro, plus PTR_TO_PID() and makes use of it wherever we maintain processes in a hash table. Previously we sometimes used LONG_TO_PTR() and other times ULONG_TO_PTR() for that, hence let's make this more explicit and clean up things. --- src/basic/macro.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/basic/macro.h') diff --git a/src/basic/macro.h b/src/basic/macro.h index 627d768b76..cbc3ca97b8 100644 --- a/src/basic/macro.h +++ b/src/basic/macro.h @@ -298,6 +298,9 @@ static inline unsigned long ALIGN_POWER2(unsigned long u) { #define PTR_TO_GID(p) ((gid_t) (((uintptr_t) (p))-1)) #define GID_TO_PTR(u) ((void*) (((uintptr_t) (u))+1)) +#define PTR_TO_PID(p) ((pid_t) ((uintptr_t) p)) +#define PID_TO_PTR(p) ((void*) ((uintptr_t) p)) + #define memzero(x,l) (memset((x), 0, (l))) #define zero(x) (memzero(&(x), sizeof(x))) -- cgit v1.2.3-54-g00ecf
