"Save a \"core image\", i.e. enough information to restart a Lisp
process later in the same state, in the file of the specified name.
:TOPLEVEL
The function to run when the created core file is resumed. The
default function handles command line toplevel option processing
- and runs the top level read-eval-print loop. This function should
- not return.
+ and runs the top level read-eval-print loop. This function returning
+ is equivalent to (SB-EXT:EXIT :CODE 0) being called.
+
+ TOPLEVEL functions should always provide an ABORT restart: otherwise
+ code they call will run without one.
:EXECUTABLE
If true, arrange to combine the SBCL runtime and the core image
This is also passed to the PURIFY function when :PURIFY is T.
(rarely used)
+ :COMPRESSION
+ This is only meaningful if the runtime was built with the :SB-CORE-COMPRESSION
+ feature enabled. If NIL (the default), saves to uncompressed core files. If
+ :SB-CORE-COMPRESSION was enabled at build-time, the argument may also be
+ an integer from -1 to 9, corresponding to zlib compression levels, or T
+ (which is equivalent to the default compression level, -1).
+
+ :APPLICATION-TYPE
+ Present only on Windows and is meaningful only with :EXECUTABLE T.
+ Specifies the subsystem of the executable, :CONSOLE or :GUI.
+ The notable difference is that :GUI doesn't automatically create a console
+ window. The default is :CONSOLE.
+
The save/load process changes the values of some global variables:
*STANDARD-OUTPUT*, *DEBUG-IO*, etc.
This is reinitialized to reflect the working directory where the
saved core is loaded.
