+ 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

+
+ By keeping PDCLib's errno in the _PDCLIB_* namespace, the library is capable
+ to "translate" between errno values used by the hosting operating system and
+ those used and passed out by the library.
+
+ Example: In the example platform, the remove() function uses the unlink()
+ system call as backend. Linux sets its errno to EISDIR if you try to unlink()
+ a directory, but POSIX demands EPERM. Within the remove() function, you can
+ catch the 'errno == EISDIR', and set '_PDCLIB_errno = _PDCLIB_EPERM'. Anyone
+ using PDCLib's <errno.h> will "see" EPERM instead of EISDIR (the _PDCLIB_*
+ prefix removed by <errno.h> mechanics).
+
+ If you do not want that kind of translation, you might want to "match" the
+ 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.
+
+ 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.

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
