RE: alarm() not working as expected

I'm using Scott's ERROR_H copy for below, which looks like below:

 /define ERRNO_H           


I'm also using Scott K's example to set the alarm action, see below:
 ******************************************************************

C                   callp     Qp0sEnableSignals()                  
C                   callp     sigemptyset(act.sa_mask)             
C                   callp     sigaddset(act.sa_mask: SIGALRM)      
C                   eval      act.sa_handler = %paddr(gotAlarm)    
C                   eval      act.sa_flags   = 0                   
C                   eval      act.sa_sigaction = *null             
C                   callp     sigaction(SIGALRM: act: *omit)

I don't see your declaration for the errno thing.
But mine looks like this:

     D m_nErrNo        S             10I 0 Based(pErrNo)
     C                   eval      pErrNo = errno()
     C                   callp     joblog(%str(strerror(m_nErrNo)))


Where errno is the raw, C language function. Which returns a pointer to
the error number, hence the assignment to the based pointer. The
actually error number is then available in the m_nErrNo field.
