WHAT IS IT?
-----------
Libping is a small C library designed to allow a programmer to 
make ICMP_ECHO requests and network services inquiries directly 
from a script or program. The library includes support for pinging 
HTTP/HTTPS, POP3, and SMTP services. The distribution includes 
ring, a script-friendly utility linked to the library and intended 
to be invoked directly from scripts. Unlike most ping utilities, 
libping will timeout on both unreachable hosts and unreachable 
networks. It returns a value every time it is called, a feature 
which makes programming ICMP echo requests simpler and more 
reliable.
