CPI-C Calls
Check_For_Completion (cmchck)
Chapter 3134
If more than one call has completed since the application last issued
Check_For_Completion or Wait_For_Conversation, issuing
Check_For_Completion more than once does not necessarily return
information about additional calls; it simply indicates that at least one
call has completed, and therefore a subsequent Wait_For_Conversation
call will return immediately and not block. Each Wait_For_Conversation
call returns one incomplete operation; if there are multiple incomplete
operations (on different conversations), the application can issue a
further Check_For_Completion after Wait_For_Conversation to check
whether further calls have completed.
The Wait_For_Conversation call does not necessarily return the
information for the same call that was reported by
Check_For_Completion.
