What is the function like system() that return the result of execution instead of printing the result on the terminal.

ex:

result = system("/usr/local/md5 1234");

I want to get the result of the md5 command, not a return status.

Thank you for you help

FILE *popen(const char *command, const char *type)

See man popen

'type' is determines if the FILE is open for reading or writing just like the fopen function.

> FILE *fp = popen("/usr/local/md5 1234", "r");
> # Now read from fp
