set function-library of external-function function-name to string-expression set function-library of creator of opaque-type-name to string-expression
set function-library of can be used to dynamically set the name of an external function library of an
external function or external creator function during the running of an OmniMark program. The string-expression should evaluate to a valid external library name for the platform on which the program is
executing. Any change will take effect the next time the external function is invoked, or the next time an
instance of the
opaque data type is created.
