absl::GetStackFrames

extern
int
GetStackFrames(
    void** result,
    int* sizes,
    int max_depth,
    int skip_count);

Description

Example:

main() { foo(); } foo() { bar(); } bar() { void* result[10]; int sizes[10]; int depth = absl::GetStackFrames(result, sizes, 10, 1); }

The current stack frame would consist of three function calls: bar(), foo(), and then main(); however, since the GetStackFrames() call sets skip_count to 1, it will skip the frame for bar(), the most recently invoked function call. It will therefore return 2 and fill result with program counters within the following functions:

result[0]foo() result[1]main()

(Note: in practice, a few more entries after main() may be added to account for startup processes.)

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.
