Currently it is -- supported on Sparc/Solaris, GNU/Linux, Windows NT, HP-UX and Tru64. -- The routines provided in this package assume that your application has -- been compiled with debugging information turned on, since this information -- is used to build a symbolic traceback. -- -- In order to retrieve symbolic information, functions in this package will -- read on disk all the debug information of the current executable and load -- them in memory, causing a significant cpu and memory overhead. -- -- This package is not intended to be used within a shared library, -- symbolic tracebacks are only supported for the main executable -- and not for shared libraries. -- -- You should consider using off-line symbolic traceback instead, using -- addr2line or gdb. with Ada.Exceptions; use Ada.Exceptions; package GNAT.Traceback.Symbolic is pragma Elaborate_Body (Traceback.Symbolic); ------------------------ -- Symbolic_Traceback -- ------------------------ function Symbolic_Traceback (Traceback : Tracebacks_Array) return String; -- Build a string containing a symbolic traceback of the given call chain. function Symbolic_Traceback (E : Exception_Occurrence) return String; -- Build a string containing a symbolic traceback of the given exception -- occurrence. end GNAT.Traceback.Symbolic;
