TMF_BEGINTAG_FROM_TXHANDLE_

This procedure returns the begin-transaction-tag associated with the specified

transaction handle. The returned tag matches the one returned by the

BEGINTRANSACTION procedure, if the calling process began the transaction. It also

matches the tag returned by AWAITIO[X] to indicate completion of a nowaited

ENDTRANSACTION call.

If the specified transaction handle does not refer to a transaction begun or resumed by

the calling process, the file system error number 715 (invalid transaction handle) is

returned.
