Get the resource manager ID

When specifying how user-defined routines register and unregister a data source using the ax_reg() or ax_unreg() function, you can use the mi_xa_get_xadatasource_rmid() function to get the resource manager ID that was previously created in the database for an XA-compliant, external data source.

The mi_xa_get_xadatasource_rmid() function can be used while invoking the ax_reg() or the ax_unreg() function in subsequent calls.

The syntax for the function is:

mi_integer mi_xa_get_xadatasource_rmid(mi_string *xasrc)

The xasrc parameter is the user-defined name of the XA data source.

For example:

     #include "xa.h"
     #include "milib.h"
     int   rmid;
   rmid = mi_xa_get_xadatasource_rmid("informix.Newyork");
  if (rmid  <= 0)
       {
        /* Error while getting XA data source id */
       }
/* Successful */
