-- A routine for dumping memory to either standard output or standard error.
-- Uses GNAT.IO for actual output (use the controls in GNAT.IO to specify
-- the destination of the output, which by default is Standard_Output).
with System;
package GNAT.Memory_Dump is
pragma Preelaborate;
type Prefix_Type is (Absolute_Address, Offset, None);
procedure Dump
(Addr : System.Address;
Count : Natural);
-- Dumps indicated number (Count) of bytes, starting at the address given
-- by Addr. The coding of this routine in its current form assumes the case
-- of a byte addressable machine (and is therefore inapplicable to machines
-- like the AAMP, where the storage unit is not 8 bits). The output is one
-- or more lines in the following format, which is for the case of 32-bit
-- addresses (64-bit addresses are handled appropriately):
--
-- 0234_3368: 66 67 68 . . . 73 74 75 "fghijklmnopqstuv"
--
-- All but the last line have 16 bytes. A question mark is used in the
-- string data to indicate a non-printable character.
procedure Dump
(Addr : System.Address;
Count : Natural;
Prefix : Prefix_Type);
-- Same as above, but allows the selection of different line formats.
-- If Prefix is set to Absolute_Address, the output is identical to the
-- above version, each line starting with the absolute address of the
-- first dumped storage element.
--
-- If Prefix is set to Offset, then instead each line starts with the
-- indication of the offset relative to Addr:
--
-- 00: 66 67 68 . . . 73 74 75 "fghijklmnopqstuv"
--
-- Finally if Prefix is set to None, the prefix is suppressed altogether,
-- and only the memory contents are displayed:
--
-- 66 67 68 . . . 73 74 75 "fghijklmnopqstuv"
