RE: Read from and Write to the same socket from two threads

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hi Charles,

While calling send() in one thread and recv() in another thread is safe,
order of winsock functions in two threads on one socket handle might cause
other issues. It's recommended to provide thread safety yourself. Please
see winsock FAQ on this:

Winsock Programmer's FAQ: Intermediate Winsock Issues
(http://tangentsoft.net/wskfaq/intermediate.html#threadsafety)


Hope this helps.
