Absolutely; but this has nothing to do with TCHAR at all, we need a convenient way to specify Unicode strings in any case.
Indeed, the two issues are orthogonal.
Since my Linux box is down for a few days now, here is some untested code trying to implement the teststr() idea.
wine/tests.h:
/*-----------------------------------------------------------*/ /* The teststr() function iterates through a set of strings */ /* with a certain set of characteristics. When the set is */ /* exausted, it returns NULL. The sets are identified by a */ /* constants defined later in the header, with the prefix */ /* TSC_. Typical usage of the function is as follows: */ /* TCSTR tstr = TSC_XXX; */ /* while ( tstr = teststr(tstr) ) */ /* <code which uses tstr> */ /* Simply replate T with A/W for encoding specific code. */ /*-----------------------------------------------------------*/ LPCWSTR teststrW(LPCWSTR wstr); LPCSTR teststrA(LPCSTR astr);
/* the TESTSTR.class field defines the class of strings */ /* in the future, we can have a union which holds additional */ /* parameters for the given class of strings. */ typedef struct tagTESTSTRW { int class; LPCWSTR str; } TESTSTRW, *LPTESTSTRW;
typedef struct tagTESTSTRA { int class; LPCSTR str; } TESTSTRA, *LPTESTSTRA;
#define _TSCT(cls, strtype, t) \ extern TESTSTR##t tsc_##cls##t; \ LPC##strtype const TSC_##cls##t = &(tsc_##cls##t.str)
#define _TSC(cls) \ _TSCT(cls, WSTR, W); \ _TSCT(cls, STR, A)
#define STR2TESTSTR(str) (LPTESTSTR)( ((void*)str) - \ ((void*)&tsc_ANYA.str) - ((void*)&tsc_ANYA) )
/* constants defining the test string sets #define TSC_ANY _TSC(ANY) #define TSC_XXX .....
teststr.c:
#define BEGINA (LPCSTR)(-1) #define BEGINW (LPCWSTR)(-1)
TESTSTRA tsc_ANYA = { 0, BEGINA }; TESTSTRW tsc_ANYW = { 0, BEGINW }; ....
LPCSTR teststrA(LPCSTR str) { LPTESTSTR tstr = STR2TESTSTR(str); if (tstr.str == BEGINA) ... <here we can do a lot of things> }
<similarly for teststrW>
Now, should I go more into the details of the implementation? Is everyone convinced that the interface is (1) simple, (2) useful, (3) implementable?
