[Dev-C++] detecting net connected pc

[Horst R. <hr...@un...>]

Hi,

is there any way to detect whether a PC is connected with a LAN. Recently 
the function: 

bool __stdcall FileExist(char* s)
{
struct _finddata_t f;
long hFile;
hFile = _findfirst(s, &f);
_findclose(hFile);
return (hFile == -1 ? 0 : -1);
} // FileExist 

does it. But now,  it does not. 

Thanks for every tip 

greetings Horst
