* Microsoft-specific extensions to the Windows NT IPX/SPX Windows
|

|
|
* Sockets interface. These extensions are provided for use as
|
||
|
|
* necessary for compatibility with existing applications. They are
|
||
|
|
* otherwise not recommended for use, as they are only guaranteed to
|
||

|
||

|
* uses these * extensions may not work over other IPX/SPX
|

|
* implementations. Include this header file after winsock.h and
|
||
|
|
* wsipx.h.
|
||
|
|
*
|
||
|
|
* To open an IPX socket where a particular packet type is sent in
|
||
|
|
* the IPX header, specify NSPROTO_IPX + n as the protocol parameter
|
||
|
|
* of the socket() API. For example, to open an IPX socket that
|
||
|
|
* sets the packet type to 34, use the following socket() call:
|
||
|
|
*
|
||
|
|
* s = socket(AF_IPX, SOCK_DGRAM, NSPROTO_IPX + 34);
|
||
|

*
|
||
|
|
* Below are socket option that may be set or retrieved by specifying
|
||
|
|
* the appropriate manifest in the "optname" parameter of getsockopt()
|
||
|
|
* or setsockopt(). Use NSPROTO_IPX as the "level" argument for the
|
||
|
|
* call.
