// PURPOSE: This module deals with stack traces:  getting them, 
// traversing them, and printing them.
//--------------------------------------------------------------------

#include "pub_tool_stacktrace.h"

// Variant that gives a little more control over the stack-walking
// (this is the "worker" function that actually does the walking).
// If you know what the thread ID for this stack is, send that
// as the first parameter, else send zero.  This helps generate
// better stack traces on ppc64-linux and has no effect on other
// platforms.
//
// The acquired IP values are placed in
// ips[0 .. min(n_ips,return_value)].  If sps and fps are non-NULL,
// the corresponding frame-pointer and stack-pointer values for each
// frame are stored there.
