Look in the OS API reference under "Virtual File System Manager". Here's some code to wet your appetite: ---------------- Char* filename = "/helloworld.txt"; Char* text = "Hello world"; // Normally you enumerate through the available volumes using VFSVolumeEnumerate. // We assume the volume ref is 1 here. UInt16 volRefNum = 1; // Create file VFSFileCreate(volRefNum, filename); // Open file FileRef fileRef; VFSFileOpen(volRefNum, filename, vfsModeWrite, &fileRef); UInt32 numBytes = StrLen(text); UInt32 written; // Normally you'd call VFSFileWrite in a loop. VFSFileWrite(fileRef, numBytes, text, &written); // Close file VFSFileClose(fileRef); ---------------- Working with VFS in a real application is a bit more involved, of course.
