Errno Codes by Platform

(copied from http://www.ioplex.com/~miallen/errcmp.html which is now down)

An identifier is defined for platforms that have a numeric value listed (even though there may not be an associated message shown). Column 2 is a score that indicates the fraction of platforms on which the identifier is found (1 meaning all). See also the Popular Errno Codes by Platform page which displays only errno identifiers that are found on all systems (excluding MS Windows).

[1] AIX ENOTEMPTY is 17 "Directory not empty" if _ALL_SOURCE and !_LINUX_SOURCE_COMPAT
[2] AIX EWOULDBLOCK is 11 "Operation would block" if _XOPEN_SOURCE_EXTENDED is 1 meaning SUS UNIX95
[3] SUSv3 states EAGAIN "Resource unavailable, try again" may be the same value as EWOULDBLOCK and indeed many of the platforms listed here have the same value.

[5] FreeBSD EDEADLK 11 "Resource deadlock avoided" used to be EAGAIN
[*] HP-UX must define EDOM and ERANGE somewhere as they are ANSI C. I have to investigate why they weren't defined in the main errno header
