SYNOPSIS

 int WSAEnumProtocolsW

 )

DESCRIPTION

Retrieves information about specified set of active network protocols.

PARAMS

`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.

RETURNS

Success: number of WSAPROTOCOL_INFO structures in buffer.

Failure: SOCKET_ERROR.

NOTES

NT4SP5 does not return SPX if protocols == NULL.

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
