CPI-C Calls
Set_Conversation_Security_User_ID (cmscsu)
Chapter 3242
State When Issued
The conversation must be in Initialize state.
State Change
There is no state change.
Usage Notes
If the return code is not CM_OK, the security_user_ID and
security_user_ID_length conversation characteristics are unchanged.
A user ID that is not valid is not detected until the allocation request,
generated by the Allocate call, is sent to the partner LU. The error is
returned to the invoking program on a subsequent call.
