WinSock Zero-Length Packet Not Sent on Network (161179)
The information in this article applies to:
This article was previously published under Q161179 SYMPTOMS
In Windows 95, if the Windows Sockets Send() function is used to send
zero-length packets using a stream-oriented socket over IPX/SPX, the
function returns a success status, but no packet is sent on the network.
CAUSE
The WinSock specifications do not require that a Send() function with a
length of zero actually result in a packet being sent over the network
when the Send() function is called on a stream-oriented socket. Windows
95 does not actually send a packet across the network when the Send()
function is called with a length of zero over a stream-oriented socket
over SPX/IPX.
RESOLUTIONSTATUS
This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit http://www.microsoft.com/windows.
MORE INFORMATION
According to the WinSock 2.0 specification, calling the Send() function
with a length of zero is to be treated by implementations as successful.
In this case, the Send() function may return 0 as a valid return value.
For message-oriented sockets, a zero-length transport datagram is sent.
