Blocking, IP sockets, and select?

» close window

The Question is:

 
Using TCPIP Services for OpenVMS Alpha v5.0A,
how can you make stdin "non-blocking" using
ioctl()?  I'd like to use select() to determine
when something is ready to be read on stdin.
 

The Answer is :

 
  The OpenVMS Wizard would prefer to use the $qio interface,
  and particularly the AST mechanism.
 
  Note: select() is only permitted to operate (at present) with
  sockets.  It does not operate across other channels.
 
  Alternatively, take a look at:
 
    SYS$COMMON:[SYSHLP.EXAMPLES.TCPIP]TCPIP$IOCTL_ROUTINE.C.
 
  Or, using TCPIP$INETDEF.H, specify ioctl() with FIONBIO.
