也就是在CreateFile的时候打开文件名指定: “\\.\Device”就可以了. 因为代码比较短, 所以我不做注释, 相信大家看代码就能明白意思了. 另外这里读写的都是软盘A盘第0扇区, 如果想读写其他的扇区, 那么可以使用API SetFilePointer. 读扇区的方法(下面的代码演示从A盘的第0扇区读出数据, 写入到文件BOOT.BIN中): #include <windows.h> #include <assert.h> #include <stdio.h> void main() { HANDLE hFile; hFile = CreateFile("\\\\.\\A:", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL); assert(hFile && "CreateFile failed!"); PBYTE pBuffer = (PBYTE)malloc(512); assert(pBuffer && "Allocate memory failed!"); DWORD dwLen; ReadFile(hFile, pBuffer, 512, &dwLen, NULL); FILE * fp; fp = fopen("boot.bin", "wb"); assert(fp && "Open file failed!"); fwrite(pBuffer, 512, 1, fp); fclose(fp); CloseHandle(hFile); free(pBuffer); } 那么相应的, 写扇区的方法的就是这样的咯(以下代码演示从BOOT.BIN中读出数据写入到A盘第0扇区): #include <windows.h> #include <assert.h> #include <stdio.h> void main() { HANDLE hFile; hFile = CreateFile("\\\\.\\A:", GENERIC_WRITE, FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); assert(hFile && "CreateFile failed!"); PBYTE pBuffer = (PBYTE)malloc(512); assert(pBuffer && "Allocate memory failed!"); FILE * fp; fp = fopen("boot.bin", "rb"); assert(fp && "Open file failed!"); fread(pBuffer, 512, 1, fp); fclose(fp); DWORD dwLen; WriteFile(hFile, pBuffer, 512, &dwLen, NULL); CloseHandle(hFile); free(pBuffer); }
