|
|
* With MSVC, code using the C support library from one version of MSVC
|
|
|
|
* cannot use file descriptors or FILE *'s returned from code using
|
|
|
|
* the C support library from another version of MSVC.

2015-11-06 19:19:45 +00:00
|
|
|
* We therefore provide our own versions of the routines to open files,
|
|
|
|
* so that they're built to use the same C support library as our code
|
|
|
|
* that reads them.
|
|
|
|
*
|
|
|
|
* (If both were built to use the Universal CRT:
|
|
|
|
*
|
|

* http://blogs.msdn.com/b/vcblog/archive/2015/03/03/introducing-the-universal-crt.aspx
|
|
|
|
*
|
|
|
|
* this would not be a problem.)
|
|
|
|
*
|
|
|
|
* DO NOT USE THESE FUNCTIONS DIRECTLY, USE ws_open() AND ALIKE FUNCTIONS
|
|
|
|
* FROM file_util.h INSTEAD!!!
|
|
|
|
*
|
|
|
|
* The following code is stripped down code copied from the GLib file
|
|
|
|
* glib/gstdio.h - stripped down because this is used only on Windows
|
|
|
|
* and we use only wide char functions.
|
|
|
|
*
|
|
|
|
* In addition, we have our own ws_stdio_stat64(), which uses
|
|
|
|
* _wstati64(), so that we can get file sizes for files > 4 GB in size.
|
|
|
|
*
|
|
|
|
* XXX - is there any reason why we supply our own versions of routines
|
|
|
|
* that *don't* return file descriptors, other than ws_stdio_stat64()?
|
|
|
|
* Is there an issue with UTF-16 support in _wmkdir() with some versions
|
|
|
|
* of the C runtime, so that if GLib is built to use that version, it
|
|
|
|
* won't handle UTF-16 paths?

* calls unlink() for files and rmdir() for directories. On Windows,
|
|
|
|
* although remove() in the C library only works for files, this
|
|
|
|
* function tries first remove() and then if that fails rmdir(), and
|
|
|
|
* thus works for both files and directories. Note however, that on
|
|
|
|
* Windows, it is in general not possible to remove a file that is
|
|
|
|
* open to some process, or mapped into memory.
|
|
|
|
*
|
|
|
|
* If this function fails on Windows you can't infer too much from the
|
|
|
|
* errno value. rmdir() is tried regardless of what caused remove() to
|
|
|
|
* fail. Any errno value set by remove() will be overwritten by that
|
|
|
|
* set by rmdir().
|
|
|
|
*
|
2008-05-22 15:46:27 +00:00
