Get real path of application from pid?

How can I get the process details like name of application & real path of application from process id?

I am using Mac OS X.


  • It's quite easy to get the process name / location if you know the PID, just use proc_name or proc_pidpath. Have a look at the following example, which provides the process path:

    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <errno.h>
    #include <libproc.h>
    int main (int argc, char* argv[])
        pid_t pid; int ret;
        char pathbuf[PROC_PIDPATHINFO_MAXSIZE];
        if ( argc > 1 ) {
            pid = (pid_t) atoi(argv[1]);
            ret = proc_pidpath (pid, pathbuf, sizeof(pathbuf));
            if ( ret <= 0 ) {
                fprintf(stderr, "PID %d: proc_pidpath ();\n", pid);
                fprintf(stderr, "    %s\n", strerror(errno));
            } else {
                printf("proc %d: %s\n", pid, pathbuf);
        return 0;
