Faster way to check if there is internet connection in C?
 

Hi,

I would like to check before doing some networking/backup stuffs that internet is available.
(c pure programming lang. (not in c++))

I could find some solution but arent adapted to Linux so much.

Would you know the best way?

for instance, in bash, i use :
libcurl is not portable much.

I would that it works as well under ms windows.

regards

Something like this? http://en.wikibooks.org/wiki/C_Progr...orking_in_UNIX

The Beej's guide is also often cited as C network programming reference http://beej.us/guide/bgnet/

the quite problem is that which likely not working with a regular limited portable (windows / Unix ) env : gcc -lncurses simple.c

netinet is not into pdcurses.dll

It compiles well under debian.

I will try under windows... and let you know. lets cross fingers

I despise Windows, but unfortunately I to have to develop software that works under it. For Windoze, you will need a different header file, which I believe is winsock2.h (perhaps winsock.h?):

hopefully we can do it without winock windoze and io stuffs :)

lets ... see.

we keep in touch since we have same concern: portability

I have made several functions that work for both platfomr: nix and win. we can chat

Maybe I don't get the point, but curses has nothing to do with network stuff. lncurses is unique to *nixes if not mistaken though.
