EEL Function Calls

This section describes how to call the EEL functions from a user program written in C or assembly language.

- C language

When an EEL function is called from a user program in C language in the same way as a normal C function is

called, the EEL function’s parameters are passed to the EEL as arguments and the required processing is

performed.

- Assembly language

Before calling an EEL function from a user program in assembly language, take necessary procedures (such as

setting parameters or return addresses) based on the function-calling rules for the C compiler package used by the

user as a development environment. The EEL function’s parameters are passed to the EEL as arguments and the

required processing is performed.

Remarks 1: To call the EEL functions offered by the EEL from a user program, you should define the following

standard header file and include it in that program:

C language

fdl.h: FDL header file

fdl_types.h: FDL definition setting header file

eel.h: EEL header file

eel_types.h: EEL definition setting header file

Assembly language

fdl.inc: FDL header file

eel.inc: EEL header file

eel_types.inc: EEL definition setting header file

Remarks 2: If an EEL function other than EEL_Init is called before EEL_Init is called, the correct operation is not guaranteed.

Remarks 3: If an EEL function other than FDL_Init is called before FDL_Init is called, the correct operation is not guaranteed.
