Store output of system call to a variable

[depsibob]

Hi,

Writing a C program in unix, and
I want to do this system call "system (uptime)" and
store the output in a variable in C.
Is it possible ?
Or do I have to do something like this:
"system(uptime > /tmp/file1)" and then read the
file "file1" fom my C program.

You can either do that (redirect the output to a file in your system() call and then parse the file) or better, use popen(). See man popen.
