+ values used by PDCLib with those used by the host OS, to avoid confusion.
The C standard only defines three distinct errno values: ERANGE, EDOM, and
EILSEQ. The standard leaves it up to "the implementation" whether there are
- any more beyond those three. There is some controversy as to whether errno is
- such a good idea at all, so you might want to come up with a different error
- reporting facility for your platform.
-
- Things used to say "Since errno values beyond the three defined by the
- standard are not portable anyway (unless you look at POSIX), having your own
- error reporting facility would not hurt anybody either." at this point.
- However, then somebody birthed C++11 into the world, which copied POSIX's
- errno values into C++. Yes, even EINTR. Therefore, this library defines
- them. That said, thats nothing stopping you from using your own error
- reporting facility for things outside the C library.
+ any more beyond those three.
+
+ However, C++11 introduced the whole list of POSIX errno values into the
+ standard, so PDCLib might as well define those as well.
Sometimes the standard says to set errno to indicate an error, but does not
prescribe a value. We will use a value from the following list. If POSIX
defines a value, we use that; otherwise, we use as seems suitable.
-
- If porting to a system which uses an errno-like reporting system (e.g. a
- UNIX), you'll probably want to define them to match what the OS uses
