The Question is:
I read in the TCPIP doc that mixing IPC and QIO is illegal. I'm wondering if
there are exceptions. Is it legal to use sys$qio() instead of connect() in an
app that otherwise only uses the TCPIP socket IPC API? Sys$qio allows multiple
simultaneous connecti
on attempts to a remote node with redundant interfaces. Connect() allows only
one at a time. (The QIO channel can be obtained using decc$get_dsc()).
Thank you very much.
The Answer is :
The OpenVMS Wizard strongly recommends using either the socket API
or the $qio API for a particular socket/channel, and would tend to
recommend against intermixing different levels of the I/O stack on
the same socket/channel. (That said, the vaxc$get_sdc call may be
of interest.) Intermixing different types of socket/channel I/O
calls across multiple sockets/channels active within the same
application is reasonable.
