2195.0. "Socket descriptor propagation question" by PRSSOS::COSTEUX (Le Plat Pays qui est le mien...) Tue May 20 1997 05:37

    A customer states that on the DECC-V4.0 documentation ("exec
    processing" on chapter 5-2-1) one mention that the sockets descriptors are
    not dupplicated from the parent process to the child process. On the
    DECC-V5.3 this restriction is no more mentioned. Does it mean that with
    this version the sockets descriptors are now duplicated from the
    parent process to the child one ?
    
    Thanks for any advice.

    Jean-Pierre,
    
      Duplicating open files and sockets from the parent to the child
      process is a runtime function and depends more on the version of
      OpenVMS than the version of the compiler.  The headers and the
      documentation ship with the compiler, the runtime library with
      the operating system.
    
      Beginning in OpenVMS V7.0, sockets are duplicated in the child 
      process.  For those users and ISV's which need to support earlier
      versions of OpenVMS, the DEC C V5.6 compiler offers an object
      library called DECC$CRTL.OLB which is equivalent to the OpenVMS
      V7.1 object library (including socket inheritance).  This library
      is available only as an object library whose objects are linked
      with the application.
