foreign-address

Arguments: name

The use of this function is deprecated because the value it returns may not be valid after a dumplisp and may not be valid if the foreign function is redefined by loading a modified (or new) so/sl/dll file. In the presence of multiprocessing, such a redefinition can in theory happen at any time. (In a non-SMP Lisp, you can protect against unexpected redefinitions by preventing other processes from running. That is much, much harder in an SMP Lisp.)

This function returns the foreign address of function. function should be a function defined by defforeign or def-foreign-call. The address of the entry point of the foreign function in the foreign code is returned. If foreign-address cannot find a foreign address for function, then an error is signaled.
