RT_SIGSUSPEND(2)                     Linux Programmer's Guide                    RT_SIGSUSPEND(2)



NAME
       rt_sigsuspend  - Replace the signal mask for a value with the unewset value until a signal
       is received

SYNOPSIS
       long sys_rt_sigsuspend (sigset_t *unewset, size_t sigsetsize, struct pt_regs regs);
                               Opteron

       long sys_rt_sigsuspend (sigset_t *unewset, size_t sigsetsize, struct pt_regs regs);
                               pSeries

       long sys_rt_sigsuspend (sigset_t *unewset, size_t sigsetsize); xSeries

       long sys_rt_sigsuspend (struct pt_regs *regs, sigset_t *unewset, size_t sigsetsize); s390


DESCRIPTION
       rt_sigsuspend replaces the signal mask for the process with the unewset value until a sig-
       nal is received. sigsetsize should indicate the size of a sigset_t type. In some architec-
       tures, the struct pt_regs regs is used to indicate interrupts.


RETURN VALUE
       rt_sigsuspend always returns -1 with the EINTR value.


ERRORS
       -EINVAL
              An invalid signal was specified.


       -EFAULT
              unewset pointed to memory that is not part of the process address.


       -EITR  The system call was interrupted.
