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" end GNAT.Memory_Dump;
