Hello group,<br />
<br />
I'm new to socket programming in C (Linux) and currently trying to retrieve a page which works fine as long as there argument is only something like <a href="http://www.example.com" rel="ugc">www.example.com</a>&nbsp;but &nbsp;for instance if I pass:<br />
<br />
myprog &nbsp; <a href="http://www.example.com" rel="ugc">www.example.com</a><br />
<br />
the code returns the html page contents and all tags ...<br />
<br />
<br />
but if I use it as <br />
<br />
myprog &nbsp;<a href="http://www.example.com/corporate/aboutus.php" rel="ugc">www.example.com/corporate/aboutus.php</a><br />
<br />
It won't work if I add a / or page at the end of it. Any idea why?<br />
<br />
<br />
Your help is appreciated.<br />
<br />
Regards.<br />
<br />
<br />
It seems in new IPv6 I should use getaddrinfo() but since I'm using somebody's else code so don't want to change it too much.<br />

Question on gethostbyname() function

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.
