Entry Point Subroutine Names

Each user exit has an associated entry point name that you use in your subroutine. You write the code for the entry point subroutine using the specified name. For example, if you decide to use the create part user exit, the associated entry point name is ufcre. The entry point name is the function name that you use in your program.  All of the entry point subroutine names take the same number of parameters.
 
NOTE: The subroutine ufusr uses a different parameter list when it is used as a user exit as opposed to an internal Open C API routine. The parameter lists for all user exit entry points use three parameters for C and C++ routines. We use the generic name entry_point to show the parameter list. The actual entry point names are given in the table for user exits (see  table ).
