-// 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]; |
-// int sizes[10]; |
-// int depth = GetStackFrames(result, sizes, 10, 1); |

-// The GetStackFrames call will skip the frame for "bar". It will |
-// return 2 and will produce pc values that map to the following |
-// procedures: |
-// 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. |
