The `-data-read-memory-bytes' Command

-------------------------------------

Synopsis

........

      -data-read-memory-bytes [ -o BYTE-OFFSET ]

        ADDRESS COUNT

where:

`ADDRESS'

     An expression specifying the address of the first memory word to be

     read.  Complex expressions containing embedded white space should

     be quoted using the C convention.

`COUNT'

     The number of bytes to read.  This should be an integer literal.

`BYTE-OFFSET'

     The offsets in bytes relative to ADDRESS at which to start

     reading.  This should be an integer literal.  This option is

     provided so that a frontend is not required to first evaluate

     address and then perform address arithmetics itself.

   This command attempts to read all accessible memory regions in the

specified range.  First, all regions marked as unreadable in the memory

map (if one is defined) will be skipped.  *Note Memory Region

Attributes::.  Second, {No value for `GDBN'} will attempt to read the

remaining regions.  For each one, if reading full region results in an

errors, {No value for `GDBN'} will try to read a subset of the region.

   In general, every single byte in the region may be readable or not,

and the only way to read every readable byte is to try a read at every

address, which is not practical.   Therefore, {No value for `GDBN'} will

attempt to read all accessible bytes at either beginning or the end of

the region, using a binary division scheme.  This heuristic works well

for reading accross a memory map boundary.  Note that if a region has a

readable range that is neither at the beginning or the end, {No value

for `GDBN'} will not read it.

   The result record (*note GDB/MI Result Records::) that is output of

the command includes a field named `memory' whose content is a list of

tuples.  Each tuple represent a successfully read memory block and has

the following fields:

`begin'

     The start address of the memory block, as hexadecimal literal.

`end'

     The end address of the memory block, as hexadecimal literal.

`offset'

     The offset of the memory block, as hexadecimal literal, relative to

     the start address passed to `-data-read-memory-bytes'.

`contents'

     The contents of the memory block, in hex.

{No value for `GDBN'} Command

.............................

The corresponding {No value for `GDBN'} command is `x'.

Example

.......

     (gdb)

     -data-read-memory-bytes &a 10

     ^done,memory=[{begin='0xbffff154',offset='0x00000000',

                   end='0xbffff15e',

                   contents='01000000020000000300'}]
