I think it should be in the .c file. These headers are
only used INSIDE the function (and not need for
passing argument), so it will speed up compilation :
asl.h will not be readed for compiling all stuff that
include your .h

Should be openned before you use this function.
It's means you should check inside your function if
libraries are open or ... use autoopen capability of
many compilers.

In myfunctions.c !

The rule is :
- if it's something used by the interface (struct,
typedef, etc ... used in the .h file) the place is in
the header.
- if not, it's in the .c file.
