Thanks for the suggestion. Looking at the doc BPX1ATM seems to be for attaching a TCB to a process, which is not our situation. We need to attach a TCB to a TCB and pass the new TCB an ECB in the usual way. However, I will bear it in mind!

Recoding to use threads and semaphores would effectively be rewriting the server - I'll think I'll leave that for the next generation! It's a bit poor that IBM's SSL implementation does not properly support traditional MVS programs; it's a part of TCP/IP, after all. I tried experimenting with BPX1SDD (set_dub_default) to make TCB's processes and threads but I still got the EDC5167I. > Thanks > Robin > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] > On Behalf Of David Crayford > Sent: 17 March 2016 21:18 > To: [email protected] > Subject: Re: Linking C module with SSL > On 17/03/2016 10:05 PM, Robin Atwood wrote: > > Now I have hit the problem I thought might be lurking. The module I fixed before with the POSIX(ON) pragma is the listener. It attaches a number of worker tasks it givesockets an incoming session to. When the worker does its takesocket it must then do a gsk_secure_socket_open() to start the SSL handshake. This failed with a EDC5167I so I added the POSIX(ON) pragma. Restarting, the STC immediately failed in a call to BPX1MSS, rc=156, rsn= 0D070201, which means: > I take it you are attaching your subtasks using MVS services.

For example, fopen()'s decision on what is a legacy dataset and what is a UNIX file changes. I was surprised to see that DD:SYSPRINT was now the name of a new UNIX file and happily created it under /u/!
