  Timeout on terminal read I/O? (C, $qio) 
 The Question is:
 
Is it possible to perform a terminal device read with a timeout without
resorting to a QIO system call from DEC C.
 
Ideally I would like to use to Unix like read () function. The reason is to
keep my code as portable as possible.
 
 
 
 
 The Answer is:
 
  Without details of the particular UNIX-like read function(s)
  desired, this question is rather difficult to answer -- that
  said, the I/O interfaces do tend to be rather platform-specific.
  This is possible via sys$qio.  There may be other approaches,
  depending on the particular C function(s) required.
