[Seed7-users] Beginner questions

[L. S. <lsp...@gm...>]

The official documentation is not bad, quite good actually, but it's like
it's not really enough for a beginner. So I appreciate any answer I get.

I'm trying to write a program to read elf-files. I can read the headers of
32bit files but would like to extend it a bit. 64bit will be easy to add
afterwards.

1. Currently I read the data and then extracts every field from the string.
I wrote my own function to handle little-endian but with bytedata.s7i
<http://seed7.sourceforge.net/libraries/bytedata.htm> it all got much
cleaner and easier. But...Could I read the data directly into my structure
(like in C
and ASM) or do I always have to insert it myself?

2. When I read the section table (from the elf file) I get some types and
would like to have an array of pointers to functions. If the type is 1 I
call myarray[1](), if it is 2 I call myarray[2](); Can I do that? I can use
a 'case-statement' but when you have many possibilities it becomes a bit
long.

3. How does "type" work? Is it just like "typedef"? Is it just an alias?
