' (1) I have never used WS_SELECT (select), therefore I must warn that I do
' not know if fd_set and timeval are properly defined.
' (2) Alot of the functions are declared with “buf as any”, when calling these
' functions you may either pass strings, byte arrays or UDT's. For 32bit I
' I recommend Byte arrays and the use of memcopy to copy the data back out
' (3) The async functions (wsaAsync*) require the use of a message hook or
' message window control to capture messages sent by the winsock stack. This
' is not to be confused with a CallBack control, The only function that uses
' callbacks is WSASetBlockingHook()
' (4) Alot of “helper” functions are provided in the file for various things
' before attempting to figure out how to call a function, look and see if
' there is already a helper function for it.
' (5) Data types (hostent etc) have kept there 16bit definitions, even under 32bit
' windows due to the problem of them not working when redfined following the
' suggested rules. 此文妙哉，快快看全文 »
