Running telnet commands from a C program

Dear All,

Is it possible to run telnet commands from a C program.

I know that there is a well known piece of freeware called expect that will do this and a module in perl that can also do this, but has anyone done in C and could you provide a small example.

Cheers,

Joseph.

Re: Running telnet commands from a C program

Hi!
It is no difficult. Look at "man" of
functions: execve,execv, execl, execle
Here is simple example of
C-source of executing command "whoami":

function
{ execlp("/usr/bin/whoami","whoami",NULL);
return 0;}

Re: Running telnet commands from a C program

And also,
The easiest way to execute a shell-command is to use standard library routine "system".
It takes only 1 argument:

main() {
int stat;
stat = system("date")
/* another rows ...... */
}
