逻辑驱动器个数和盘符获取GetLogicalDrives和GetLogicalDriverStrings

获取逻辑驱动器有两个函数GetLogicalDrives和GetLogicalDriverStrings

MSDN：GetLogicalDrives函数介绍

MSDN ：GetLogicalDriverStrings函数介绍

一、盘符和标卷的获取 GetLogicalDriverStrings

// ConsoleApplication3.cpp : 定义控制台应用程序的入口点。
//#include "stdafx.h"
#include    
#include    #define BUFSIZE 1024int main(int   argc, char   **argv)
{TCHAR VolumeName[256];TCHAR szLogicDriveStrings[BUFSIZE];PCHAR szDrive;ZeroMemory(szLogicDriveStrings, BUFSIZE);GetLogicalDriveStrings(BUFSIZE - 1, szLogicDriveStrings);szDrive = (PCHAR)szLogicDriveStrings;/*方法二,采用do循环才能GetDriveType(szDrive);do{UINT uDriverType;printf("\n%s\n", szDrive);uDriverType = GetDriveType(szDrive);switch (uDriverType){case DRIVE_UNKNOWN:printf("The driver type cannot be determined!");break;case DRIVE_NO_ROOT_DIR:printf("The root path is invalid,for example,no volume is mounted at the path");break;case DRIVE_REMOVABLE:printf("The drive is a type that has removable media,for example:a floppy drive or removable hard disk");break;case DRIVE_FIXED:printf("The drive is a type that cannot be removed, for example,a fixed hard drive");break;case DRIVE_REMOTE:printf("This drive is a remote(network) drive");break;case DRIVE_CDROM:printf("This drive is a CD-ROM drive.");break;case DRIVE_RAMDISK:printf("This drive is a RAM disk");break;default:break;}szDrive += (lstrlen(szDrive) + 1);} while (*szDrive != '\x00');*/while(*szDrive){GetVolumeInformation(szDrive, VolumeName, 255, NULL, NULL, NULL, NULL, NULL);printf("%s的卷标：%s\n ", szDrive, VolumeName);szDrive+= (_tcslen(szDrive) + 1);}//system("PAUSE");return   0;
}

二，个数获取GetLogicalDrives

// ConsoleApplication3.cpp : 定义控制台应用程序的入口点。
//#include "stdafx.h"
#include    
#include    #define BUFSIZE 1024
int main()
{DWORD temp;char disk_path[5] = { 0 };int count = 0;int diskmount = 0;temp = GetLogicalDrives();while (temp != 0){if ((temp & 1) != 0)//if ((temp & 0x1) == 1){sprintf_s(disk_path, "%c:", 'A' + count);printf("%s \n", disk_path);diskmount++;}temp >>= 1;count++;}printf("驱动器个数：%d\n", diskmount);return 0;
}
