save_program/[1,2]
save_program(
+File)
save_program(
+File,
+Goal)
Saves the state of the current execution in QOF format to File. A goal, Goal, to be called upon execution/restoring of the saved state, may be specified.
save_program/[1,2]
creates a QOF representation of all predicates in
all modules existing in the system. However, it does not save the user's
pre-linked code.
It also saves such states of the system as operator definitions, prolog_flags,
debugging and advice state, and initializations. Object files dynamically
loaded into the system are saved in the qof file as object dependencies.
The resulting file is executable, and can be started up as a command,
or can be restored using restore/1
.
save_program/[1,2]
saves module import/export information, which gets
reinstated when File is loaded. No new module-importation will be
done when File is loaded, because it is assumed that it was done
before save_program/[1,2]
was called. Thus if your program consists of one
or more modules, and you save it with save_program/[1,2]
, loading the
resulting File into some new module will not import any of your
predicates into that module. If you want to save out a module such
that it will be imported automatically into any module from which it
is loaded, then use save_modules/2
.
