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  un-
       ewset value until a signal is received. sigsetsize should indicate the
       size of a sigset_t type. In some	 architectures,	 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 ad-
	      dress.


       -EITR  The system call was interrupted.
