From 685e40bb09f5f24a2af54ea09c97328808f76990 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 19 Mar 2011 21:36:10 -0400 Subject: syscall overhaul part two - unify public and internal syscall interface with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights. --- src/thread/__wait.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/thread/__wait.c') diff --git a/src/thread/__wait.c b/src/thread/__wait.c index 8c249cd3..b0969bb2 100644 --- a/src/thread/__wait.c +++ b/src/thread/__wait.c @@ -1,4 +1,3 @@ -#define SYSCALL_RETURN_ERRNO #include "pthread_impl.h" void __wait(volatile int *addr, volatile int *waiters, int val, int priv) @@ -11,6 +10,6 @@ void __wait(volatile int *addr, volatile int *waiters, int val, int priv) } if (waiters) a_inc(waiters); while (*addr==val) - syscall4(__NR_futex, (long)addr, FUTEX_WAIT|priv, val, 0); + __syscall(__NR_futex, (long)addr, FUTEX_WAIT|priv, val, 0); if (waiters) a_dec(waiters); } -- cgit v1.2.1
