ad_get_tcl_call_stack (public)

 ad_get_tcl_call_stack [ level ]

Defined in packages/acs-tcl/tcl/utilities-procs.tcl

Returns a stack trace from where the caller was called. See also ad_print_stack_trace which generates a more readable stack trace at the expense of truncating args.

level (defaults to "-2") - The level to start from, relative to this proc. Defaults to -2, meaning the proc that called this proc's caller. Per default, don't show "ad_log", when this calls ad_get_tcl_call_stack.
