If we don't find a match for the window using the regular content-type guessing code (#1950), use the parent pid.

by default.
See Find parent pid given a pid: requires libproc-dev
.
#include <proc/readproc.h> void printppid(pid_t pid) { proc_t process_info; get_proc_stats(pid, &process_info); printf("Parent of pid=%d is pid=%d\n", pid, process_info.ppid); }
