Problem with fasm

Hi All,
                  There is a complicated issue here. I have downloaded
fasm source of a driver and want to integrate it to my kernel.
However, there is a problem:

1. If i call a FASM function from within C code (kernel), it is not
able to return back to the next line in C Code
2. If i call a NASM function from within C Code, it works properly (it
returns back to next line in C Code)

Here are the code snippets:

NASM:

global <func name>

<func name>:
             ret


FASM:

public <func name>

<func name>:
          ret


Is there a global keyword or similar stuff in FASM?
