求大神详解！！！！
#include <windows.h>
#include <string.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE;
char DirSpec[MAX_PATH]; // directory specification
DWORD dwError;

printf ("Target directory is %s.\n", argv[1]);
strncpy (DirSpec, argv[1], strlen(argv[1])+1);
strncat (DirSpec, "\\*", 3);

hFind = FindFirstFile(DirSpec, &FindFileData);
if (hFind == INVALID_HANDLE_VALUE)
{
printf ("Invalid file handle. Error is %u\n", GetLastError());
return (-1);
}
else
{
printf ("First file name is %s\n", FindFileData.cFileName);
while (FindNextFile(hFind, &FindFileData) != 0)
{
printf ("Next file name is %s\n", FindFileData.cFileName);
}

dwError = GetLastError();
FindClose(hFind);
if (dwError != ERROR_NO_MORE_FILES)
{

printf ("FindNextFile error. Error is %u\n", dwError);
return (-1);
}
}
return (0);
}
