Value Description

CMRE_SUCCESS

The call succeeded.

CMRE_INVALID_CONNECTION

The connection does not exist.

CMRE_INVALID_PARAMETER

CMRE_OUT_OF_MEMORY

Remarks

This function is called by the Connection Manager and processed by the Connection Service Provider.

This function first determines the differences between the two configuration structures, pTypeSpecificInfoPrevious and pTypeSpecificInfoNew, and the configuration that is currently active.

If pTypeSpecificInfoPrevious is different from the configuration that is currently active, an error is returned.

If the supplied configuration structures are different, the differences are analyzed and applied to the configuration that is currently active.
