.Sh DESCRIPTION
|
|
|
|
|
.Nm binpatch
|
|
|
|
|
is used to modify or examine the data associated with a symbol in a binary
|
|
|
|
|
file
|
|
|
|
|
.Ar binfile .
|
|
|
|
|
The flags
|
|
|
|
|
.Fl b ,
|
|
|
|
|
.Fl w
|
|
|
|
|
and
|
|
|
|
|
.Fl l
|
|
|
|
|
specify the size of the data to be modified or examined
|
|
|
|
|
(byte, word and long respectively.) The
|
|
|
|
|
.Ar binfile
|
|
|
|
|
is scanned in search of the symbol
|
|
|
|
|
.Ar symname
|
|
|
|
|
(specified with the
|
|
|
|
|
.Fl s

If the symbol is found the current data and address are printed. Next if the
|
|
|
|
|
.Fl r
|
|
|
|
|
flag has been given, the current data is replaced with that of
|
|
|
|
|
.Ar value .
|

|
.Pp
|
|
|
|
|
If the second form is used the address
|
|
|
|
|
.Ar addr
|
|
|
|
|
specified with the
|
|
|
|
|
.Fl a
|
|
|
|
|
flag is used as a direct address into the data section of the binary and
|
|
|
|
|
no symbol search is performed.
|
|
|
|
|
.Pp
|
|
|
|
|
The
|
|
|
|
|
.Fl o
|
|
|
|
|
flag specifies an offset in byte, word or long (
