Instructs the DTC Proxy to enlist on behalf of the XA resource manager. The EnlistResourceManager method must be called for every transaction that the connection is requested to be enlisted in. This interface method should be called after the XA resource manager has the XID.

When called, a message is sent to the XA TM module in DTC, which then enlists with the DTC TM module. At the time of two-phase commit, this enlistment receives the prepare, commit, and abort messages which the XA TM module translates into appropriate XA function calls such as xa_prepare, xa_commit, and xa_abort.

If this method fails, the ODBC driver must call ReleaseResourceManager using the cookie specified in dwRMCookie.
