In unix environments * this is no problem, because the used shared libraries * format (elf) supports this immediatly. Under Windows * this isn't true, because a functions address in a dll * is different from the same function in another dll or * applications, because the used Portable Executable * File adds a code stub to each client to provide the * exported symbol name. This stub uses an indirect * pointer to get the original symbol address, which is * then jumped to, like in this example: * * --- client --- --- dll ---- * ... * call foo * * foo: jmp (*_imp_foo) ----> foo: .... * nop * nop * * _imp_foo: .long * * Now it is clear why the clients symbol foo isn't the same * as in the dll and we can think about how to deal which * this two above mentioned requirements, to export this * symbol to all clients and to allow calling this symbol * as a function. The solution I've used exports the * symbol _XtInherit as data symbol, because global data * symbols are exported to all clients. But how to deal * with the second requirement, that this symbol should * be used as function. The Trick is to build a little * code stub in the data section in the exact manner as * above explained. This is done with the assembler code * below. * * Ralf Habacker * * References: * msdn http://msdn.microsoft.com/msdnmag/issues/02/02/PE/PE.asp * cygwin-xfree: http://www.cygwin.com/ml/cygwin-xfree/2003-10/msg00000.html */ asm (".data\n\ .globl __XtInherit \n\ __XtInherit: jmp *_y \n\ _y: .long ___XtInherit \n\ .text \n"); #define _XtInherit __XtInherit #endif void _XtInherit(void) { XtErrorMsg("invalidProcedure","inheritanceProc",XtCXtToolkitError, "Unresolved inheritance operation", (String *)NULL, (Cardinal *)NULL); } void XtToolkitInitialize(void) { static Boolean initialized = False; LOCK_PROCESS; if (initialized) { UNLOCK_PROCESS; return; } initialized = True; UNLOCK_PROCESS; /* Resource management initialization */ XrmInitialize(); _XtResourceListInitialize(); /* Other intrinsic intialization */ _XtConvertInitialize(); _XtEventInitialize(); _XtTranslateInitialize(); /* Some apps rely on old (broken) XtAppPeekEvent behavior */ if(getenv("XTAPPPEEKEVENT_SKIPTIMER")) XtAppPeekEvent_SkipTimer = True; else XtAppPeekEvent_SkipTimer = False; } String _XtGetUserName( String dest, int len) { #ifdef WIN32 String ptr = NULL; if ((ptr = getenv("USERNAME"))) { (void) strncpy (dest, ptr, len-1); dest[len-1] = '\0'; } else *dest = '\0'; #else #ifdef X_NEEDS_PWPARAMS _Xgetpwparams pwparams; #endif struct passwd *pw; char* ptr; if ((ptr = getenv("USER"))) { (void) strncpy (dest, ptr, len-1); dest[len-1] = '\0'; } else { if ((pw = _XGetpwuid(getuid(),pwparams)) != NULL) { (void) strncpy (dest, pw->pw_name, len-1); dest[len-1] = '\0'; } else *dest = '\0'; } #endif return dest; } static String GetRootDirName( String dest, int len) { #ifdef WIN32 register char *ptr1; register char *ptr2 = NULL; int len1 = 0, len2 = 0; if (ptr1 = getenv("HOME")) { /* old, deprecated */ len1 = strlen (ptr1); } else if ((ptr1 = getenv("HOMEDRIVE")) && (ptr2 = getenv("HOMEDIR"))) { len1 = strlen (ptr1); len2 = strlen (ptr2); } else if (ptr2 = getenv("USERNAME")) { len1 = strlen (ptr1 = "/users/"); len2 = strlen (ptr2); } if ((len1 + len2 + 1) < len) sprintf (dest, "%s%s", ptr1, (ptr2) ? ptr2 : ""); else *dest = '\0'; #else #ifdef X_NEEDS_PWPARAMS _Xgetpwparams pwparams; #endif struct passwd *pw; static char *ptr; if (len <= 0 || dest == NULL) return NULL; if ((ptr = getenv("HOME"))) { (void) strncpy (dest, ptr, len-1); dest[len-1] = '\0'; } else { if ((ptr = getenv("USER"))) pw = _XGetpwnam(ptr,pwparams); else pw = _XGetpwuid(getuid(),pwparams); if (pw != NULL) { (void) strncpy (dest, pw->pw_dir, len-1); dest[len-1] = '\0'; } else *dest = '\0'; } #endif return dest; } static void CombineAppUserDefaults( Display *dpy, XrmDatabase *pdb) { char* filename; char* path; Boolean deallocate = False; if (!(path = getenv("XUSERFILESEARCHPATH"))) { #if !defined(WIN32) || !defined(__MINGW32__) char *old_path; char homedir[PATH_MAX]; GetRootDirName(homedir, PATH_MAX); if (!(old_path = getenv("XAPPLRESDIR"))) { char *path_default = "%s/%%L/%%N%%C:%s/%%l/%%N%%C:%s/%%N%%C:%s/%%L/%%N:%s/%%l/%%N:%s/%%N"; if (!(path = ALLOCATE_LOCAL(6*strlen(homedir) + strlen(path_default)))) _XtAllocError(NULL); sprintf( path, path_default, homedir, homedir, homedir, homedir, homedir, homedir ); } else { char *path_default = "%s/%%L/%%N%%C:%s/%%l/%%N%%C:%s/%%N%%C:%s/%%N%%C:%s/%%L/%%N:%s/%%l/%%N:%s/%%N:%s/%%N"; if (!(path = ALLOCATE_LOCAL( 6*strlen(old_path) + 2*strlen(homedir) + strlen(path_default)))) _XtAllocError(NULL); sprintf(path, path_default, old_path, old_path, old_path, homedir, old_path, old_path, old_path, homedir ); } deallocate = True; #endif } filename = XtResolvePathname(dpy, NULL, NULL, NULL, path, NULL, 0, NULL); if (filename) { (void)XrmCombineFileDatabase(filename, pdb, False); XtFree(filename); } if (deallocate) DEALLOCATE_LOCAL(path); } static void CombineUserDefaults( Display *dpy, XrmDatabase *pdb) { #ifdef __MINGW32__ char *slashDotXdefaults = "/Xdefaults"; #else char *slashDotXdefaults = "/.Xdefaults"; #endif char *dpy_defaults = XResourceManagerString(dpy); if (dpy_defaults) { XrmCombineDatabase(XrmGetStringDatabase(dpy_defaults), pdb, False); } else { char filename[PATH_MAX]; (void) GetRootDirName(filename, PATH_MAX - strlen (slashDotXdefaults) - 1); (void) strcat(filename, slashDotXdefaults); (void)XrmCombineFileDatabase(filename, pdb, False); } } /*ARGSUSED*/ static Bool StoreDBEntry( XrmDatabase *db, XrmBindingList bindings, XrmQuarkList quarks, XrmRepresentation *type, XrmValuePtr value, XPointer data) { XrmQPutResource((XrmDatabase *)data, bindings, quarks, *type, value); return False; } static XrmDatabase CopyDB(XrmDatabase db) { XrmDatabase copy = NULL; XrmQuark empty = NULLQUARK; XrmEnumerateDatabase(db, &empty, &empty, XrmEnumAllLevels, StoreDBEntry, (XPointer)©); return copy; } /*ARGSUSED*/ static String _XtDefaultLanguageProc( Display *dpy, /* unused */ String xnl, XtPointer closure) /* unused */ { if (! setlocale(LC_ALL, xnl)) XtWarning("locale not supported by C library, locale unchanged"); if (!
