+
=head2 Script Portability on Cygwin
Cygwin does an outstanding job of providing UNIX-like semantics on top of
contains a backslash or drive letter is a Win32 pathname (and not subject
to the translations applied to POSIX style pathnames).
+For conversion we have C<Cygwin::win_to_posix_path()> and
+C<Cygwin::posix_to_win_path()>.
+
+Pathnames may not contain Unicode characters. C<Cygwin> still uses the
+ANSI API calls and no Unicode calls because of newlib deficiencies.
+There's an unofficial unicode patch for cygwin at
+F<http://www.okisoft.co.jp/esc/utf8-cygwin/>
+
=item * Text/Binary
When a file is opened it is in either text or binary mode. In text mode
a file is subject to CR/LF/Ctrl-Z translations. With Cygwin, the default
-mode for an open() is determined by the mode of the mount that underlies
-the file. Perl provides a binmode() function to set binary mode on files
-that otherwise would be treated as text. sysopen() with the C<O_TEXT>
-flag sets text mode on files that otherwise would be treated as binary:
+mode for an C<open()> is determined by the mode of the mount that underlies
+the file. See C<Cygwin::is_binmount()>. Perl provides a C<binmode()> function
+to set binary mode on files that otherwise would be treated as text.
+C<sysopen()> with the C<O_TEXT> flag sets text mode on files that otherwise
+would be treated as binary:
sysopen(FOO, "bar", O_WRONLY|O_CREAT|O_TEXT)
-lseek(), tell() and sysseek() only work with files opened in binary mode.
+C<lseek()>, C<tell()> and C<sysseek()> only work with files opened in binary
+mode.
The text/binary issue is covered at length in the Cygwin documentation.
+=item * PerlIO
+
+PerlIO overrides the default Cygwin Text/Binary behaviour. A file will
+always be treated as binary, regardless of the mode of the mount it lives
+on, just like it is in UNIX. So CR/LF translation needs to be requested in
+either the C<open()> call like this:
+
+ open(FH, ">:crlf", "out.txt");
+
+which will do conversion from LF to CR/LF on the output, or in the
+environment settings (add this to your .bashrc):
+
+ export PERLIO=crlf
+
+which will pull in the crlf PerlIO layer which does LF -> CRLF conversion
+on every output generated by perl.
+
=item * F<.exe>
-The Cygwin stat(), lstat() and readlink() functions make the F<.exe>
+The Cygwin C<stat()>, C<lstat()> and C<readlink()> functions make the F<.exe>
extension transparent by looking for F<foo.exe> when you ask for F<foo>
(unless a F<foo> also exists). Cygwin does not require a F<.exe>
extension, but I<gcc> adds it automatically when building a program.
in a makefile) the F<.exe> is not transparent. The I<install> included
with Cygwin automatically appends a F<.exe> when necessary.
-=item * chown()
+=item * Cygwin vs. Windows process ids
+
+Cygwin processes have their own pid, which is different from the
+underlying windows pid. Most posix compliant Proc functions expect
+the cygwin pid, but several Win32::Process functions expect the
+winpid. E.g. C<$$> is the cygwin pid of F</usr/bin/perl>, which is not
+the winpid. Use C<Cygwin::winpid_to_pid()> and C<Cygwin::winpid_to_pid()>
+to translate between them.
+
+=item * Cygwin vs. Windows errors
-On WinNT chown() can change a file's user and group IDs. On Win9x chown()
+Under Cygwin, $^E is the same as $!. When using L<Win32 API Functions|Win32>,
+use C<Win32::GetLastError()> to get the last Windows error.
+
+=item * C<chown()>
+
+On WinNT C<chown()> can change a file's user and group IDs. On Win9x C<chown()>
is a no-op, although this is appropriate since there is no security model.
=item * Miscellaneous

+File locking using the C<F_GETLK> command to C<fcntl()> is a stub that

+therefore Perl adds the suffix C<.bak> automatically if you use C<perl -i>
+without specifying a backup extension.
+
+Using C<fork()> after loading multiple dlls may fail with an internal cygwin
+error like the following:

-On WinNT Cygwin provides setuid(), seteuid(), setgid() and setegid().
+On WinNT Cygwin provides C<setuid()>, C<seteuid()>, C<setgid()> and C<setegid()>.
