一个遍历驱动器的c代码

最近看到Windows编程的获取驱动器信息的一些东西,就熟练下相关的API调用,增强对c的熟练程度,具体代码如下:

 

 

#include <stdio.h> #include <stdlib.h> #include <windows.h> #define BUFSIZE 1024  BOOL GetDirverInfo(LPSTR szDriver); void main() {     CHAR szLogicalDriverStrings[BUFSIZE] = {0};     PCHAR szDriver = NULL;     ZeroMemory(szLogicalDriverStrings,BUFSIZE);     GetLogicalDriveStrings( (BUFSIZE - 1),szLogicalDriverStrings);     szDriver = (PCHAR) szLogicalDriverStrings;     do     {         if ( ! GetDirverInfo(szDriver) )         {             printf("\n得到卷信息错误:%d",GetLastError() );         }         szDriver += ( lstrlen(szDriver) + 1 );     } while (*szDriver != '\x00');     getchar(); } BOOL GetDirverInfo(LPSTR szDriver) {     UINT nDriverType;     CHAR szDriverName[MAX_PATH];     DWORD nVolumeSerialNumber;     DWORD nMaximumComponentLength;     DWORD nFileSystemFlags;     CHAR szFileSystemNameBuffer[MAX_PATH];     nDriverType = GetDriveType(szDriver);     switch (nDriverType)     {     case DRIVE_UNKNOWN:         printf("%s","未知的驱动器");         break;     case DRIVE_NO_ROOT_DIR:         printf("%s","根路径无效驱动器");         break;     case DRIVE_REMOVABLE:             printf ("%s","可插拔的驱动器");             break;     case DRIVE_CDROM:                 printf("%s","光驱驱动");                 break;     case DRIVE_RAMDISK:                 printf("%s","硬盘驱动");                 break;     default:         printf("%s","其他类型");     }              if ( !GetVolumeInformation(         szDriver,         szDriverName,         MAX_PATH,         &nVolumeSerialNumber,         &nMaximumComponentLength,         &nFileSystemFlags,         szFileSystemNameBuffer,         BUFSIZE         ) )     {               goto EXIT0;              }     if ( 0 != lstrlen(szDriverName) )     {         printf("\n驱动器名字 是 %s\n",szDriverName);     }     printf("\n 卷的序列号是 %u\n",nVolumeSerialNumber);     printf("\n 最大元件长度是 %u\n",nMaximumComponentLength);     printf("\n 文件系统类型是 %s\n",szFileSystemNameBuffer);    return true; EXIT0:    return false; }
