Whilst trying to convert cmd to Unicode, I've stumbled across a problem which I either need to work around or fix, and I am not sure which.
WCHAR h[] = {'h','e','l','l','o','\0'}; WCHAR fmt[] = {':', '%', '1', '0','s',':','\0'}; char test[255]; WCHAR result[255];
sprintf(test, "'%10s'", "hello"); sprintfW(result, fmt, h); WINE_FIXME("%s vs %s\n", test, wine_dbgstr_w(result));
Gives: fixme:cmd:WCMD_list_directory ' hello' vs L":hello:"
ie sprintf of %10s means right justified field of 10 characters sprintfW of %10s gives left justified field of n characters
(I haven't tried if the string is > 10, as I don't care...)
Basically, the format strings in cmd rely on the padding behaviour. Is this a bug in sprintfW which needs fixing, or should I work around it?
Unfortunately, looking in the code to lib\wine\string.c, it just copies the field and ignores justification or min/max width precisions for strings, and as it is used all over the place there's also a concern of what would be changed by fixing it.
Any suggestions for a workable alternative?
