TCHAR* to char*

Error : argument of type "TCHAR *" is incompatible with parameter of type "const char *" error in line : if(remove( f ) != 0 )

我想将"TCHAR f[MAX_PATH]"转换为const char *并传递给"删除"功能：

int _tmain(int argc, TCHAR *argv[])
{
WIN32_FIND_DATA ffd;
LARGE_INTEGER filesize;
TCHAR szDir[MAX_PATH];
size_t length_of_arg;
HANDLE hFind = INVALID_HANDLE_VALUE;
DWORD dwError=0;
TCHAR s[MAX_PATH];
TCHAR f[MAX_PATH];
// If the directory is not specified as a command-line argument,
// print usage.
if(argc != 2)
{
_tprintf(TEXT("nUsage: %s <directory name>n"), argv[0]);
goto l;
}
// Check that the input path plus 2 is not longer than MAX_PATH.
StringCchLength(argv[1], MAX_PATH, &length_of_arg);
if (length_of_arg > (MAX_PATH - 2))
{
_tprintf(TEXT("nDirectory path is too long.n"));
goto l;
}
_tprintf(TEXT("nTarget directory is %snn"), argv[1]);
// Prepare string for use with FindFile functions.  First, copy the
// string to a buffer, then append '*' to the directory name.
StringCchCopy(szDir, MAX_PATH, argv[1]);
StringCchCopy(s, MAX_PATH, szDir);
StringCchCat(szDir, MAX_PATH, TEXT("\*"));
// Find the first file in the directory.
hFind = FindFirstFile(szDir, &ffd);
if (INVALID_HANDLE_VALUE == hFind)
{
ErrorHandler(TEXT("FindFirstFile"));
return dwError;
}
// List all the files in the directory with some info about them.
StringCchCat(s, MAX_PATH, TEXT("/"));
do
{
if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
_tprintf(TEXT("  %s   <DIR>n"), ffd.cFileName);

}
else
{
StringCchCopy(f, MAX_PATH, s);
StringCchCat(f, MAX_PATH, ffd.cFileName);
filesize.LowPart = ffd.nFileSizeLow;
filesize.HighPart = ffd.nFileSizeHigh;
_tprintf(TEXT("  %s   %ld bytesn"), ffd.cFileName, filesize.QuadPart);
_tprintf(f);
if(remove( f ) != 0 )
perror( "Error deleting file" );
else
puts( "File successfully deleted" );
}
}
while (FindNextFile(hFind, &ffd) != 0);
dwError = GetLastError();
if (dwError != ERROR_NO_MORE_FILES)
{
ErrorHandler(TEXT("FindFirstFile"));
}
FindClose(hFind);
return dwError;
l:
getch();
}
