The xa_end() function

For each XA data source participating in a transaction, the xa_end() function is called before a direct rollback or before the prepare stage for a commit operation.

The syntax for the function is:

mint xa_end (XID *xid,    /* IN */
          mint rmid,     /* IN */
          int4 flags)   /* IN */

Table 1. The xa_end() parameters
Parameter	Description
xid	Pointer to the XID data structure that is defined in the xa.h file and used for the current transaction
rmid	Unique resource manager identifier
flags	`TMSUCCESS`, when commit issued, or `TMFAIL`, indicating the transaction will be rolled back

The following code fragment contains the xa_end() function:

#include "xa.h"
mint mqseries_end(XID *xid, mint rmid, int4 flags)
  {
/*  Error  */
   return XAER_RMERR;
/* Success */
  return XA_OK;
}

For valid return values, refer to X/Open information, including Distributed Transaction Processing: The XA Specification.
