ppelleti / strings returned by FormatMessage
Created February 8, 2013 01:30
A comparison of the error strings returned by evutil_socket_error_to_string, versus the error strings returned by the Windows function FormatMessage.
WSAEINTR -> "A blocking operation was interrupted by a call to WSACancelBlockingCall."
WSAEACCES -> "An attempt was made to access a socket in a way forbidden by its access permissions."
WSAEFAULT -> "The system detected an invalid pointer address in attempting to use a pointer argument in a call."
WSAEINVAL -> "An invalid argument was supplied."
WSAEMFILE -> "Too many open sockets."
WSAEWOULDBLOCK -> "A non-blocking socket operation could not be completed immediately."
WSAEINPROGRESS -> "A blocking operation is currently executing."
WSAEALREADY -> "An operation was attempted on a non-blocking socket that already had an operation in progress."
WSAENOTSOCK -> "An operation was attempted on something that is not a socket."

This is a simple program which demonstrates that OpenSSL's default random number generator is not fork-safe if the pids wrap.
/* Patrick Pelletier, public domain / cc0
*
* OpenSSL's default random number generator (RAND_SSLeay) is not
* fork-safe in the case where the child pids wrap around without the
* parent having used or reseeded the RNG in the interim. Which makes
* this a rare problem, but one which recently cropped up on Android:
* https://plus.google.com/+AndroidDevelopers/posts/YxWzeNQMJS2
* and Nikolay Elenkov wrote a program to demonstrate the bug on Android:
* https://gist.github.com/nelenkov/581f9be65dcc0b6b35b9
