"ltrace" shows that the "free" command uses a function meminfo() to get the information.
Doesn't anybody know how do I call this function directly from

free opens /proc/meminfo and filters out the info it needs. meminfo() is simply a helper function used by free, part of procps, used to obtain that info.

do an strace to see what it actually does.
