在PSDK中使用GetCurrentDirectory（）和SetCurrentDirectory（）来改变当前目录，示例如下：
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include <tchar.h>
#define BUFSIZE MAX_PATH
int _tmain(int argc, TCHAR **argv, TCHAR **envp)
{
TCHAR Buffer[BUFSIZE];
DWORD dwRet;
if(argc != 2)
{
_tprintf(TEXT("Usage: Test <dir>\n"));
return 0;
}
dwRet = GetCurrentDirectory(BUFSIZE, Buffer);
if( dwRet == 0 )
{
_tprintf(TEXT("GetCurrentDirectory failed (%d)\n"), GetLastError());
return 0;
}
if(dwRet > BUFSIZE)
{
_tprintf(TEXT("GetCurrentDirectory failed (buffer too small;need %d chars)\n"), dwRet);
return 0;
}
if( !SetCurrentDirectory(argv[1]))
{
_tprintf(TEXT("SetCurrentDirectory failed (%d)\n"), GetLastError());
return 0;
}
_tprintf(TEXT("Set current directory to %s\n"), argv[1]);
if( !SetCurrentDirectory(Buffer) )
{
_tprintf(TEXT("SetCurrentDirectory failed (%d)\n"), GetLastError());
return 0;
}
_tprintf(TEXT("Restored previous directory (%s).\n"), Buffer);
return 1;
}
本示例用vc6编译连接可行。
