Function Description
Allow the user to manually refresh the DHCP configuration parameters that were previously obtained with a DHCPINFORM request. Since no lease time is provided with an information-only server response, the parameters returned never undergo automatic renewal. If the user wishes to periodically refresh the DHCP configuration parameters or suspects that the parameters may no longer be valid (e.g. link change), the user can call this function and wait for the DHCP notification of completion.
Parameters
- interfaceHandle
- The device entry as returned by tfAddInterface().
- multiHomeIndex
- Index of the DHCP autoconfigured IPv4 address on interfaceHandle.
Returns
- TM_ENOERROR
- Success.
- TM_EINPROGRESS
- No error. Operation is in progress. User will be notified.
- TM_EINVAL
- Invalid parameter.
- TM_EPERM
- Operation not permitted in current state.
