Source[det]load_foreign_library(:FileSpec)
[det]load_foreign_library(:FileSpec, +Entry:atom)
Load a shared object or DLL. After loading the Entry function is called without arguments. The default entry function is composed from =install_=, followed by the file base-name. E.g., the load-call below calls the function install_mylib(). If the platform prefixes extern functions with =_=, this prefix is added before calling.
      ...
      load_foreign_library(foreign(mylib)),
      ...
FileSpec is a specification for absolute_file_name/3. If searching the file fails, the plain name is passed to the OS to try the default method of the OS for locating foreign objects. The default definition of file_search_path/2 searches <prolog home>/lib/<arch> on Unix and <prolog home>/bin on Windows.
