I am looking to print stack trace from within a particular function of my
driver code, that appears in windbg
whenever that code path gets hit…
Is there such an api/function to do so?

You can display a simple stack backtrace within Windbg by setting a
breakpoint at the appropriate location in your code with a command string as
a parameter. For example:
bu nt!MmCreateSection “kbn200” OR
bu nt!MmCreateSection “kbn200;g” if you don’t want to the debugger to halt.
See the section on setting breakpoints in the Windbg help file for more
info.
I’m asssuming from your question that you have a live kernel debugging
session; if, however, you are wanting to achieve the same programmatically
(without a debugger attached), it may be difficult. I haven’t researched
what debugging APIs are available in kernel-mode, but if we assume there is
such an API available(I know you can use dbghelp.dll and dbgeng.dll from
user-mode), you’d also have to ensure that all symbols are accessible at
run-time, which you may not be able to guarantee.

Thanks.
bu nt!MmCreateSection “kbn200;g”
serves my purpose…
