Socket Error Codes

Several system messages return a socket error code (Errno), which is either:

•	a valid system error code returned from the operating system, or

•	Unknown error, if the operating system has returned an error code that iProcess does not recognize.

For more information about these Errno codes, you should refer to your operating system socket documentation, as follows:

•	On UNIX, the system include file (/usr/include/sys/errno.h) provides a brief definition of each Errno. The Intro(2) man page provides a complete list of the error numbers and their names as defined in errno.h.

•	On Windows, the Windows Sockets Error Codes are documented in the MSDN. See http://msdn2.microsoft.com/en-us/library/ms740668.aspx.
