* acqdrv - acquiring driver client.
|

*
|
|
* Starts ONE global transaction (tpbegin), fires the ACQUIRE -> RECONCILE ->
|
|
* SETTLE chain via a single tpcall("ACQUIRE"), then tpcommit (or tpabort when
|
|
* the 4th arg is "abort", to prove XA rollback).
|
|
*
|
|
* Usage: acqdrv [merchant] [amount] [bizdate YYYY-MM-DD] [abort]
