那个函数是自定义的。
网上找到一段代码，不知是否合适你 BOOL GetDirverInfo(LPSTR szDrive) { UINT uDriveType; DWORD dwVolumeSerialNumber; DWORD dwMaximumComponentLength; DWORD dwFileSystemFlags; CHAR szFileSystemNameBuffer[BUFSIZE]; CHAR szDirveName[MAX_PATH]; printf("\n%s\n",szDrive); uDriveType = GetDriveType(szDrive); switch(uDriveType) { case DRIVE_UNKNOWN: printf("The drive 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("The drive is a remote (network) drive. "); break; case DRIVE_CDROM: printf("The drive is a CD-ROM drive. "); break; case DRIVE_RAMDISK: printf("The drive is a RAM disk. "); break; default: break; } if (!GetVolumeInformation( szDrive, szDirveName, MAX_PATH, &dwVolumeSerialNumber, &dwMaximumComponentLength, &dwFileSystemFlags, szFileSystemNameBuffer, BUFSIZE )) { return FALSE; } if(0!=lstrlen(szDirveName)) { printf ("\nDrive Name is %s\n",szDirveName); } printf ("\nVolume Serial Number is %u",dwVolumeSerialNumber); printf ("\nMaximum Component Length is %u",dwMaximumComponentLength); printf ("\nSystem Type is %s\n",szFileSystemNameBuffer); if(dwFileSystemFlags & FILE_SUPPORTS_REPARSE_POINTS) { printf ("The file system does not support volume mount points.\n"); } if(dwFileSystemFlags & FILE_VOLUME_QUOTAS) { printf ("The file system supports disk quotas.\n"); } if(dwFileSystemFlags & FILE_CASE_SENSITIVE_SEARCH) { printf ("The file system supports case-sensitive file names.\n"); } printf("...\n"); return TRUE; } |
下面是书上的代码，为什么用vs2010编译通不过？
#include<Windows.h>
#include<stdlib.h>
#include<stdio.h>
#define BUFSIZE 1024
BOOL GetDirverInfo(LPSTR szDrive);
void main(void)
{
CHAR szLogicalDriveStrings[BUFSIZE];
PCHAR szDrive;
ZeroMemory(szLogicalDriveStrings,BUFSIZE);
GetLogicalDriveStrings(BUFSIZE-1,szLogicalDriveStrings);
szDrive=(PCHAR)szLogicalDriveStrings;
do
{
if(!GetDirverInfo(szDrive))
{
printf("\nGet Volume Information Error:%d",GetLastError());
}
szDrive +=(lstrlen(szDrive)+1);
}
while(*szDrive!='\x00');
}
