);

If the function fails, the return value is one of the following error codes.

Value Meaning
ERROR_INVALID_PARAMETER
At least one of the following is true:
  • hMprConfig is NULL
  • dwLevel is not 0, 1, 2, or 3.
  • lpbBuffer is NULL
  • phRouterInterface is NULL

Remarks

The MprAdminInterfaceCreate function supports the MPR_INTERFACE_2 structure. However, MprConfigInterfaceCreate does not. In order to create a demand-dial interface that is persistent after a reboot, call MprAdminInterfaceCreate with MPR_INTERFACE_2, then call MprConfigInterfaceCreate with MPR_INTERFACE_0 or MPR_INTERFACE_1.
