Integration of a user exit to Oracle Forms depends on the operating system and the language used to write the foreign function.
On Microsoft Windows, you create a dynamic link library with foreign function object code files and IAPXTB control structure object code files. When a foreign function is invoked from a user exit, a dynamic link library loads into memory.
For other environments, you must rebuild the Forms Runtime executable by linking the object code files from the foreign function and IAPXTB control structure to Oracle Forms object code files.
