Since the regress tool limits ** the output to a one line status:PASS or FAIL,all of the printf statements ** have been handled with an if (debug_mode) statement. ***********************************************************************/ #include "prinit.h" /*********************************************************************** ** Includes ***********************************************************************/ /* Used to get the command line option */ #include "plgetopt.h" #include <stdio.h> #include <stdlib.h> static void PrintVersion( const char *msg, const PRVersion* info, PRIntn tab) { static const len = 20; static const char *tabs = {" "}; tab *= 2; if (tab > len) tab = len; printf("%s", &tabs[len - tab]); printf("%s ", msg); printf("%s ", info->id); printf("%d.%d", info->major, info->minor); if (0 != info->patch) printf(".p%d", info->patch); printf("\n"); } /* PrintDependency */ static void ChaseDependents(const PRVersionInfo *info, PRIntn tab) { PrintVersion("exports", &info->selfExport, tab); if (NULL != info->importEnumerator) { const PRDependencyInfo *dependent = NULL; while (NULL != (dependent = info->importEnumerator(dependent))) { const PRVersionInfo *import = dependent->exportInfoFn(); PrintVersion("imports", &dependent->importNeeded, tab); ChaseDependents(import, tab + 1); } } } /* ChaseDependents */ static PRVersionInfo hack_export; static PRVersionInfo dummy_export; static PRDependencyInfo dummy_imports[2]; static const PRVersionInfo *HackExportInfo(void) { hack_export.selfExport.major = 11; hack_export.selfExport.minor = 10; hack_export.selfExport.patch = 200; hack_export.selfExport.id = "Hack"; hack_export.importEnumerator = NULL; return &hack_export; } static const PRDependencyInfo *DummyImports( const PRDependencyInfo *previous) { if (NULL == previous) return &dummy_imports[0]; else if (&dummy_imports[0] == previous) return &dummy_imports[1]; else if (&dummy_imports[1] == previous) return NULL; } /* DummyImports */ static const PRVersionInfo *DummyLibVersion(void) { dummy_export.selfExport.major = 1; dummy_export.selfExport.minor = 0; dummy_export.selfExport.patch = 0; dummy_export.selfExport.id = "Dumbass application"; dummy_export.importEnumerator = DummyImports; dummy_imports[0].importNeeded.major = 2; dummy_imports[0].importNeeded.minor = 0; dummy_imports[0].importNeeded.patch = 0; dummy_imports[0].importNeeded.id = "Netscape Portable Runtime"; dummy_imports[0].exportInfoFn = PR_ExportInfo; dummy_imports[1].importNeeded.major = 5; dummy_imports[1].importNeeded.minor = 1; dummy_imports[1].importNeeded.patch = 2; dummy_imports[1].importNeeded.id = "Hack Library"; dummy_imports[1].exportInfoFn = HackExportInfo; return &dummy_export; } /* DummyLibVersion */ int main(int argc, char **argv) { PRIntn tab = 0; const PRVersionInfo *info = DummyLibVersion(); const char *buildDate = __DATE__, *buildTime = __TIME__; printf("Depend.c build time is %s %s\n", buildDate, buildTime); if (NULL != info) ChaseDependents(info, tab); return 0; } /* main */ /* depend.c */
