libcompat: Add a helper to get/set OS error state

2023-06-15T16:13:26+00:00

On Unix like OSes, this saves/restores errno, on Windows both errno and GetLastError state are saved/restored. This should make it simpler to preserve that across function calls. Additionally, while tracking down uses of GetLastError, some places where the error code was printed out directly where replaced with instances of w32_perror. Signed-off-by: David Oberhollenzer

Windows: redirect standard I/O and convert text to UTF-16

2022-03-10T20:53:29+00:00

Preprocessor magic is used to redirect putc/fputc/fputs/printf/fprintf to custom implementations. The custom implementations try to figure out if we are printing to the console and, if so, convert the resulting strings to UTF-16 and print them through ConsoleWriteW. If the output is redirected to a file or a pipe, the original (presummed) UTF-8 is kept. Simply setting the console output codepage to UTF-8 does not work, because the standard I/O facilities of MSVCRT either does not support unicode (in non-wchar mode), or has half-broken support through fputs, which can still break up multi-byte sequences through its internal buffering. Likewise, changing the codepage and using ConsoleWriteA, or trying to use fputws did not work in a test VM either. This approach is the one that worked most consistently among the ones tried, but also has problems. E.g. it breaks when setting the codepage to UTF-8 manually (using `chcp 65001`).

Fix Windows main wrapper after mingw upgrade

2021-12-14T19:54:40+00:00

Apparently, mingw implicitly included stdlib.h indirectly from either windows.h or shellapi.h. After an upgrade, the windows build now fails with EXIT_FAILURE being undefined. Signed-off-by: David Oberhollenzer

Add a wrapper for the main function on Windows

2021-12-05T09:29:32+00:00

A macro and forward declaration are added to compat.h that rename the main() function programs using compat.h into sqfs_tools_main. An actual main() function is added to libcompat.a, that uses the shell API to get the UTF-16 command line arguments, convert them to UTF-8 and call sqfs_tools_main.
