32 -- A routine for dumping memory to either standard output or standard error. | |
33 -- Uses GNAT.IO for actual output (use the controls in GNAT.IO to specify | |
34 -- the destination of the output, which by default is Standard_Output). | |

38 package GNAT.Memory_Dump is | |

41 type Prefix_Type is (Absolute_Address, Offset, None); | |

43 procedure Dump | |
44 (Addr : System.Address; | |
45 Count : Natural); | |
46 -- Dumps indicated number (Count) of bytes, starting at the address given | |
47 -- by Addr. The coding of this routine in its current form assumes the case | |
48 -- of a byte addressable machine (and is therefore inapplicable to machines | |
49 -- like the AAMP, where the storage unit is not 8 bits). The output is one | |
50 -- or more lines in the following format, which is for the case of 32-bit | |
51 -- addresses (64-bit addresses are handled appropriately): | |
52 -- | |
53 -- 0234_3368: 66 67 68 . . . 73 74 75 "fghijklmnopqstuv" | |
54 -- | |
55 -- All but the last line have 16 bytes. A question mark is used in the | |
56 -- string data to indicate a non-printable character. | |
57 | |
58 procedure Dump | |
59 (Addr : System.Address; | |
60 Count : Natural; | |
61 Prefix : Prefix_Type); | |
62 -- Same as above, but allows the selection of different line formats. | |
63 -- If Prefix is set to Absolute_Address, the output is identical to the | |
64 -- above version, each line starting with the absolute address of the | |
65 -- first dumped storage element. | |
66 -- | |
67 -- If Prefix is set to Offset, then instead each line starts with the | |
68 -- indication of the offset relative to Addr: | |
69 -- | |
70 -- 00: 66 67 68 . . . 73 74 75 "fghijklmnopqstuv" | |
71 -- | |
72 -- Finally if Prefix is set to None, the prefix is suppressed altogether, | |
73 -- and only the memory contents are displayed: | |
74 -- | |
75 -- 66 67 68 . . . 73 74 75 "fghijklmnopqstuv" | |
