/*
** Name: xa_start - Start/Resume binding a thread w/an XID.
**
** Description:
**
** Inputs:
** xid - pointer to XID.
** rmid - RMI identifier, assigned by the TP system, unique to the AS
** process.
** flags - TP system-specified flags, one of
** TMJOIN/TMRESUME/TMNOWAIT/TMASYNC/TMNOFLAGS.
**
** Outputs:
** Returns:
** XA_OK - normal execution.
** XA_RETRY - if TMNOWAIT is set in flags. We will *always*
** assume a blocking call and return this (Ingres65).
** XA_RB* - if this XID is marked "rollback only".
** XA_RBROLLBACK - rollback only, unspecified reason.
** XA_RBCOMMFAIL - on any error on a GCA call.
** XA_RBDEADLOCK - deadlock detected down in DBMS server.
** XA_RBINTEGRITY- integrity violation detected in DBMS server.
** XA_RBOTHER - any other reason for rollback.
** XA_RBPROTO - protocol error, this XA call made in wrong state
** for the thread/RMI.
** XA_RBTIMEOUT - the local xn bound to this XID timed out.
** XA_RBTRANSIENT- a transient error was detected by the DBMS svr.
** XAER_ASYNC - if TMASYNC was specified. We don't support
** TMASYNC (post-Ingres65 feature).
** XAER_RMERR - internal error w/gca association mgmt.
** XAER_RMFAIL - RMI made unavailable by some error.
** XAER_DUPID - XID already exists, when it's not expected to be
** "known" at this AS, i.e. it's not TMRESUME/TMJOIN.
** XAER_OUTSIDE - RMI/thread is doing work "outside" of global xns.
** XAER_NOTA - TMRESUME or TMJOIN was set, and XID not "known".
** XAER_INVAL - illegal input arguments.
** XAER_PROTO - if there are active/suspended XIDs bound to
** the RMI. Enforces XA Spec's "state table" rules.
