Function core.runtime.defaultTraceHandler
Get the default Throwable
implementation for the platform
object .Throwable .TraceInfo defaultTraceHandler
(
void* ptr = null
);
This functions returns a trace handler, allowing to inspect the current stack trace.
Parameters
Name | Description |
---|---|
ptr | (Windows only) The context to get the stack trace from.
When null (the default), start from the current frame. |
Returns
A Throwable
implementation suitable to iterate over the stack,

. If called from a finalizer (destructor), always returns null
as trace handlers allocate.
Example
Example of a simple program printing its stack trace
import core .runtime;
import core .stdc .stdio;
void main()
{
auto trace = defaultTraceHandler(null);
foreach (line; trace)
{
printf("%.*s\n", cast(int)line .length, line .ptr);
}
}
