qsave:arch_shlib/3

qsave:arch_shlib(+Architecture, +FileSpec, -File) is det[multifile, library(qsave)]: This is a user defined hook called by qsave_program/2. It is used to find a shared library for the specified Architecture, named by FileSpec. FileSpec is of the form foreign(Name), a specification usable by absolute_file_name/2. The predicate should unify File with the absolute path for the shared library that corresponds to the specified Architecture.
If this predicate fails to find a file for the specified architecture an existence_error is thrown.
