protocols [In] Pointer to NULL-terminated array of protocol id's. NULL retrieves information on all available protocols.
buffer [In] Pointer to a buffer to be filled with WSAPROTOCOL_INFO structures.
len [In/Out] Pointer to a variable specifying buffer size. On output the variable holds the number of bytes needed when the specified size is too small.

Failure: SOCKET_ERROR.

BUGS

- NT4SP5 returns in addition these list of NETBIOS protocols (address family 17), each entry two times one for socket type 2 and 5.

iProtocol szProtocol 0x80000000 \Device\NwlnkNb 0xfffffffa \Device\NetBT_CBENT7 0xfffffffb \Device\Nbf_CBENT7 0xfffffffc \Device\NetBT_NdisWan5 0xfffffffd \Device\NetBT_El9202 0xfffffffe \Device\Nbf_El9202 0xffffffff \Device\Nbf_NdisWan4.

- there is no check that the operating system supports the returned protocols
