NOTE: Currently 64-bit support is limited in the VBD library to HPUX 11.0 and Solaris 2.8 platforms, with HPUX 11.0 supporting a maximum single file size of 128 GB. As large file support and 64-bit operating systems become more prevalent support will included for all the platforms supported by the 32-bit database engine. The 64-bit API is based on the non-POSIX standard UNIX API interfaces to support large files: ::fopen64() ::fseeko64() ::ftello64() ::stat64() NOTE: Since these functions are not part of the POSIX standard they may be removed in future compiler versions. */ // ----------------------------------------------------------- // #include <iostream.h> #include <iomanip.h> #include <string.h> #include "vbfloat.h" #include "vbd64.h" #include "vbstat64.h" // Various static data area sizes used to test large files const __LLWORD__ STATIC_AREA_SIZE = (__LLWORD__)0; // 2 GIG file test // WARNING: This test requires 2.3 GIG of free disk space // const __LLWORD__ STATIC_AREA_SIZE = (__LLWORD__)2147483647; // 4 GIG file test // WARNING: This test requires 4.3 GIG of free disk space // const __LLWORD__ STATIC_AREA_SIZE = (__LLWORD__)4294967290; const int NUM_OBJECTS = 10; const int NAME_LENGTH = 128; class DatabaseObject { public: DatabaseObject() { name[0] = 0; oid = (FAU64)0, cid = (vbFLOAT64)0; } DatabaseObject(const char *s, __LLWORD__ i, double d); public: void DisplayObject(); public: // Platform independent data members char name[NAME_LENGTH]; // Fixed string type FAU64 oid; // Integer type vbFLOAT64 cid; // Floating point type }; DatabaseObject::DatabaseObject(const char *s, __LLWORD__ i, double d) { for(int j = 0; j < NAME_LENGTH; j++) name[j] = 0; // Clear the name string strcpy(name, s); oid = i; cid = d; } void DatabaseObject::DisplayObject() { cout << "Database object name: " << name << endl; cout << "Database object OID: " << oid << endl; cout.setf(ios::showpoint | ios::fixed); cout.precision(3); cout << "Database object CID: " << cid << endl; } void PausePrg() { cout << endl; cout << "Press enter to continue..." << endl; cin.get(); } int main() { vbDatabase64 *f = new vbDatabase64; const char *fname = "simple.vbd"; int i; FAU64 index[NUM_OBJECTS]; FAU64 static_area_size(STATIC_AREA_SIZE); FAU64 addr; DatabaseObject buf; int exists = 0; cout << endl; cout << "Simple demo of the file manager class." << endl; if(!vbDatabase64::Exists(fname)) { cout << "Creating new file..." << endl; f->Create(fname, static_area_size); if(CheckError(f) != 0) return 1; } else { cout << "Opening existing file..." << endl; f->Open(fname); if(CheckError(f) != 0) return 1; exists = 1; } PausePrg(); VBDStats(f); PausePrg(); if(exists == 1) { // Used for big and little endian cross-platform testing cout << "Reading the first object..." << endl; addr = f->FindFirstVB(); f->Read(&buf, sizeof(buf), addr+f->VBHeaderSize()); if(CheckError(f) != 0) return 1; buf.DisplayObject(); PausePrg(); cout << "Reading the last object..." << endl; f->Read(&buf, sizeof(buf), f->GetHighestVB()+f->VBHeaderSize()); if(CheckError(f) != 0) return 1; buf.DisplayObject(); PausePrg(); } cout << "Adding " << NUM_OBJECTS << " objects to VBD file..." << endl; cout << "Size of each object = " << sizeof(DatabaseObject) << endl; PausePrg(); for(i = 0; i < NUM_OBJECTS; i++) { // Allocate a block to store the object addr = f->Alloc(sizeof(DatabaseObject)); if(CheckError(f) != 0) return 1; // Index the object index[i] = addr; // Construct the datbase object char name[NAME_LENGTH]; sprintf(name, "Mouse %s", addr.c_str()); DatabaseObject ob(name, addr, 2000.101); // Write the object data f->Write(&ob, sizeof(DatabaseObject)); if(CheckError(f) != 0) return 1; cout << "Block Address: " << (FAU64)(addr - f->VBHeaderSize()) << endl; cout << "Writing object " << i << " to FAU64: " << addr << endl; } cout << "Wrote " << i << " to the VBD file" << endl; PausePrg(); cout << "Reading " << NUM_OBJECTS << " objects from the VBD file..." << endl; PausePrg(); for(i = 0; i < NUM_OBJECTS; i++) { f->Read(&buf, sizeof(buf), index[i]); if(CheckError(f) != 0) return 1; buf.DisplayObject(); } PausePrg(); VBDStats(f); PausePrg(); cout << "Exiting..." << endl; f->Close(); if(CheckError(f) != 0) return 1; delete f; return 0; } // ----------------------------------------------------------- // // ------------------------------- // // --------- End of File --------- // // ------------------------------- //
