TMF_GET_TX_ID_

This procedure extracts a transactional identifier (txid) from a transaction handle. The

identifier is only valid within the lifetime of the calling process or until TMF is either shut

down or crashes. The returned identifier can be used in calls to TMF_RESUME_ to

specify the transaction to be resumed by the process. The same transactional identifier

is returned by TMF_SUSPEND_.
