Intrfc.exe Programmatically Retrieves IP Interface Info. (186312)

SUMMARY

Intrfc.exe is a sample that demonstrates how to programmatically enumerate IP interface information, such as a system's IP address, subnet mask, and broadcast address, using the WSAIoctl() API with the SIO_GET_INTERFACE_LIST option. In addition, Intrfc.exe demonstrates how to interpret IP status flags for each IP interface. The flags are defined in the Windows Sockets 2 Protocol-Specific Annex specification which can be found in the January 98 MSDN Platform SDK or later.
