The “xa_switch_t” structure, described in the “xa.h” file, contains the set of entry points that enables the transaction manager to call the standard XA routines supplied by the resource manager. You use this structure to register XA entry points with the transaction manager; your TP software vendor provides the registration routine.

The “xa_switch_t” structure is declared in the “iixa.h” include file. For details about this structure, refer to the X/Open XA documentation.
