I know this is an old thread but it might help someone in the future.

#include "../pm/mproc.h"

/* inside function */

struct mproc *mp;
int i, n=0;

printf("Number of running processes:\n");

getsysinfo(PM_PROC_NR, SI_PROC_TAB, mproc);

for (i = 0; imp_pid == 0 && i != PM_PROCS_NR) continue;
    n++;   
}

printf("%d", n);

/* function end */
