binpatch is used to modify or examine the data
  associated with a symbol in a binary file binfile.
The flags -b, -w,
    -l, and -d specify the size
    of the data to be modified or examined. -b is for
    8bit (int8_t), -w is for
    16bit (int16_t), -l is for
    32bit (int32_t), and -d is
    for 64bit (int64_t) variables.
The binfile is scanned in search of the
    symbol symname (specified with the
    -s flag). If the symbol is found the current data
    and address are printed.
Next if the -r flag has been given, the
    current data is replaced with that of value.
If the second form is used the address addr
    specified with the -a flag is used as a direct
    address into the data section of the binary and no symbol search is
    performed.
The -o flag specifies an offset in
    int8_t, int16_t,
    int32_t, and int64_t
    (-b, -w,
    -l, or -d) units from the
    given locator (-s or -a) for
    binpatch to perform its described actions. This
    might be useful to patch a member of array or structure.
The -T flag is used to specify the
    starting address of a.out binary text segment. Ignored for other binary
    executable formats.
binpatch command doesn't check if size of specified
  symbol is the same as the specified size by -b,
  -w, -l, or
  -d flag.
The binpatch command doesn't check if
    specified address or symbol is a patchable variable and it might corrupt the
    specified executable binary.
