how to ping ip address from c language ?

I guess you do not like the idea of using system?
However that's the only way for doing that "portable".
However if you leave Ansi-C grounds you surely will find a acceptable
solution. See e.g

The inventor of ping, Mike Muuss, wrote the first ping program in day.. and
put it into public domain:

It's a pity that it's provided with a ".html" suffix. When I view the
page in my browser, the #include directives are messed up, and
probably other things as well.

The problem is that the <pre> directive doesn't actually say to
display plain text without interpreting it; things that look like HTML
directives are still processed.

You can download the raw file, remove everything up to and including
the "<pre>" directive, and try to compile it.

But note that the code is inherently non-portable (as it must be,
since standard C doesn't have the required facilities). Of the
headers it includes, only two are standard:

#include <stdio.h>
#include <errno.h>
#include <sys/time.h>

#include <sys/param.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/file.h>

#include <netinet/in_systm.h>
#include <netinet/in.h>
#include <netinet/ip.h>
#include <netinet/ip_icmp.h>
#include <netdb.h>

And it failed to compile on four different systems I just tried
(Cygwin, Solaris, Red Hat, AIX) -- all of which already have their own
"ping" programs, of course.

A solution to the original problem that's fairly likely to work on any
system where this is even possible is

system("ping ...");

Yeah, I used "View Source" function in the browser, or you could get the raw
page via wget... or telnet.

Hehe.. you might have better luck with BSD installation from 1983! Still
it's an interesting read of a historical hack:

As an alternative, here's the source code link from Mike's webpage

If you want the whole story about ping, Mike's page gives the scoop:
