Bjorn,
Jeff,

Thank you for your answer.

I'm going to download and try GNAT component collection; before this
Jeff I think you have reason:

The original C code looks like:
fbuffer = mmap(NULL, fix.smem_len, PROT_READ | PROT_WRITE, MAP_FILE |
MAP_SHARED, fb_fd, 0);

and I translated it into:
fbindex := mmap(0, fbhandler.fixinfo.smem_len, fbhandler.PROT_READ +
fbhandler.PROT_WRITE, fbhandler.MAP_FILE + fbhandler.MAP_SHARED, fbid,
0);

...not the same! :-) Maybe if I'll try to change the "0" to "NULL" it
will works... maybe!

There is an equivalence of the C's NULL in Ada?

Thank you again.
Francesco
