I am writing a file viewer, which will be used on different terminals in Unix environment. How can I find the current terminal type from within my C program. I tried using the following code:<br />
<br />
char *str1;<br />
<br />
str1 = (char *)(system(&quot;echo $TERM&quot;));<br />
printf(&quot;Terminal Type is: %s\r\n&quot;, str1);<br />
<br />
But, it only echos the term type on the screen, and does not send anything in the variable str1. Any suggestions??<br />

Find unix TERM within C program.

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.
