Mixing TCP/IP sockets and sys$qio calls? ioctl?

» close window

The Question is:

 
Hi Wizard,
 
I have ported a UNIX socket application to OVMS
platform using OVMS V6.2 and C compiler 5.5-003.
Unfortunatly I am finding out (Painfully) that
the the ioctl() call is not available. Also I
have found out that the sys$qiow should be used.
My question is how do I call sys$qiow using a
socket that was created via a socket and bind
call? In other words can I call mix sys$qiow()
and normal socket calls?
 
Thanks in advance

The Answer is :

 
  The ioctl call is the UNIX version of the OpenVMS sys$qio call -- it is
  how a C program communicates directly with a device driver on a UNIX
  system.
 
  Mixing ioctl and sockets with sys$qio calls is not an approach that the
  OpenVMS Wizard would generally recommend -- mixing is possible, see the
  decc$get_sdc call for the routine necessary to convert from a socket to
  an OpenVMS I/O channel.
 
  Various ioctl calls are available with OpenVMS V7.0 and later.
 
  For information on socket programming, as well as using the sys$qio
  call with TCP/IP Services, please see:
