How to get value of shell commands in variable

[Anonymous]

Hi all,
If We are excuting shell command in c program. then how can we get result of that command in variable?

For example:
int var;
var=system(“uname -r”);

This command gives OS version , But in var variable it gives exit status of that command.
But I want the OS version in variable.How can we get that?

Any idea?

Thanks in advance,
BKP
