The msqlsrvxa1 structure exposes the XA routines of MSDTC to an XA transaction manger, so MSDTC can be used as a resource manager for XA transactions. The fields of msqlsrvxa1 contain function pointers that point to the XA routines in MSDTC. msqlsrvxa1 is the MSDTC implementation of the xa_switch_t structure from the XA standard.
Syntax
Here’s how the syntax of xa_switch_t is defined in the XA standard:
struct xa_switch_t {
char name[RMNAMESZ];
long flags;
long version;
int (∗xa_open_entry)(char ∗, int, long);
int (∗xa_close_entry)(char ∗, int, long);
int (∗xa_start_entry)(XID ∗, int, long);
int (∗xa_end_entry)(XID ∗, int, long);
int (∗xa_rollback_entry)(XID ∗, int, long);
int (∗xa_prepare_entry)(XID ∗, int, long);
int (∗xa_commit_entry)(XID ∗, int, long);
int (∗xa_recover_entry)(XID ∗, long, int, long);
int (∗xa_forget_entry)(XID ∗, int, long);
int (∗xa_complete_entry)(int ∗, int ∗, int, long);
};
Members
msqlsrvxa1 contains the following function pointers:
xa_open_entry
A pointer to the xa_open routine.
xa_close_entry
A pointer to the xa_close routine.
xa_start_entry
A pointer to the xa_start routine.
xa_end_entry
A pointer to the xa_end routine.
xa_rollback_entry
A pointer to the xa_rollback routine.
xa_prepare_entry
A pointer to the xa_prepare routine.
xa_commit_entry
A pointer to the xa_commit routine.
xa_recover_entry
A pointer to the xa_recover routine.
xa_forget_entry
A pointer to the xa_forget routine.
xa_complete_entry
A pointer to the xa_complete routine.
Remarks
To use msqlsrvxa1, you must statically link to the xaswitch.lib library, and then add the following code to any C or C++ source files that need to call XA routines.
extern "C"
{
extern struct xa_switch_t msqlsrvxa1;
}
