TMF_JOIN_EXT_

This procedure allows a process to participate in a transaction, initiated by another

process, without taking over as the ENDTRANSACTION caller. TMF_JOIN_EXT_ can

be called by more than one process in any node in the beginner’s Expand network at

the same time. The BEGINTRANSACTION caller need not call TMF_SUSPEND_EXT_

before another process calls TMF_JOIN_EXT_ and can participate in the transaction at

the same time. TMF_JOIN_EXT_ is interchangeable with TMF_JOIN_ in the

beginner's node.

Joining a transaction means:



Making the transaction the current transaction.



The process calling TMF_JOIN_EXT_ is not allowed to call ENDTRANSACTION.

TMF_JOIN_EXT_ must be completed in the calling process by a call to

TMF_SUSPEND_EXT_.

Note. This procedure cannot be called by TNS applications.

Syntax for C Programmers
