2005-08-25 Tor Lillqvist <tml@novell.com> Make also the g_spawn*() functions take parameters in the GLib file name encoding, i.e. UTF-8, on Windows. Has no impact on Unix API or ABI. Like the other GLib API that was earlier changed to use UTF-8 on Windows, the names of the functions that take UTF-8 have _utf8 suffixes added by using preprocessor macros in the header file. The old names are kept for functions with the old behaviour, taking parameters in the system codepage, for DLL ABI stability. * glib/gspawn.h: On Win32 add the suffix _utf8 to the names of the g_spawn*() functions. * glib/gspawn-win32.c: Use wide-char API on NT-based Windows. Convert parameters from UTF-8 to wide chars (NT) or system codepage (Win9x) and call the C library _wspawn*() or spawn*() functions respectvely. Add DLL ABI stability versions that take parameters in the system codepage. * glib/gspawn-win32-helper.c: On NT-based Windows use the wide-char versions of argv and envp, and use wide-char API to change directory and spawn the program to run. Remove the verbose debugging output, it was too complex to modify for the wide-char features. (Just add temporary debugging printouts if needed, no need to have them permanently in the source.) * glib/gspawn.c: Corresponding documentation updates. * glib/glib.symbols: Corresponding changes: Mark the ABI stability symbols as PRIVATE, add the new _utf8-suffixed ones.
