it's nicer for the function that doesn't use errno to be independent,
and have the other one call it. saves some time and avoids clobbering
errno.
#include <signal.h>
#include <errno.h>
-#include "syscall.h"
-#include "libc.h"
-#include "pthread_impl.h"
int sigprocmask(int how, const sigset_t *set, sigset_t *old)
{
- if (how > 2U) {
- errno = EINVAL;
- return -1;
- }
- return syscall(SYS_rt_sigprocmask, how, set, old, 8);
+ int r = pthread_sigmask(how, set, old);
+ if (!r) return r;
+ errno = r;
+ return -1;
}
#include <signal.h>

int pthread_sigmask(int how, const sigset_t *set, sigset_t *old)
{
- int ret = sigprocmask(how, set, old);
- if (ret) return errno;
- return 0;
