@cindex writing into executables
@cindex writing into corefiles
By default, _GDBN__ opens the file containing your program's executable
code (or the corefile) read-only. This prevents accidental alterations
to machine code; but it also prevents you from intentionally patching
your program's binary.
If you'd like to be able to patch the binary, you can specify that
explicitly with the @code{set write} command. For example, you might
want to turn on internal debugging flags, or even to make emergency
repairs.

If you specify @samp{set write on}, _GDBN__ will open executable and
core files for both reading and writing; if you specify @samp{set write
off} (the default), _GDBN__ will open them read-only.
If you've already loaded a file, you must load it
again (using the @code{exec-file} or @code{core-file} command) after
changing @code{set write}, for your new setting to take effect.

@kindex sharedlibrary
@kindex share
@cindex shared libraries
_GDBN__ supports the SunOS shared library format. Symbols from a shared
library cannot be referenced before the shared library has been linked
with the program. (That is to say, until after you type @code{run} and
the function @code{main} has been entered; or when examining core
files.) Once the shared library has been linked in, you can use the
following commands:
_GDBN__ supports the SunOS shared library format. _GDBN__ automatically
loads symbol definitions from shared libraries when you use the
@code{run} command, or when you examine a core file. (Before you issue

function in a shared library, however---unless you're debugging a core
file).

This is an obsolescent command; you can use it to explicitly
load shared object library symbols for files matching a UNIX regular
expression, but as with files loaded automatically, it will only load
shared libraries required by your program for a core file or after
typing @code{run}. If @var{regex} is omitted all shared libraries
required by your program are loaded.
