-// Skips the most recent "skip_count" stack frames (also skips the
-// frame generated for the "GetStackFrames" routine itself), and then
-// records the pc values for up to the next "max_depth" frames in
-// "result", and the corresponding stack frame sizes in "sizes".
-// Returns the number of values recorded in "result"/"sizes".
-//
-// Example:
-//      main() { foo(); }
-//      foo() { bar(); }
-//      bar() {
-//        void* result[10];

-//      result[0]       foo
-//      result[1]       main
-// (Actually, there may be a few more entries after "main" to account for
-// startup procedures.)
-// And corresponding stack frame sizes will also be recorded:
-//    sizes[0]       16
-//    sizes[1]       16
-// (Stack frame sizes of 16 above are just for illustration purposes.)
-// Stack frame sizes of 0 or less indicate that those frame sizes couldn't
-// be identified.
-//
-// This routine may return fewer stack frame entries than are
-// available. Also note that "result" and "sizes" must both be non-NULL.
