A lightweight library for reading data from and dumping data to ini-files,
developed for embedded micro-controller environments.

It declares some structure types for mapping your mostly static data
to ini-file sections and keys.

You define the mapping between ini-entries and internal data as an ini file,
and then call uCini_gen.pl to generate the related C-code.

You can connect uCini to your system by defining an stdio_.h file,
that shall declare a small subset of the standard stdio.h:
FILE_ stdin_ stdout_ stderr_ fopen_ fclose_ fgets_ fputs_ 
This allows using uCini in small systems with no OS/file-system/C-library.

API
===

uCiniParseLine()
----------------
removes ini-punctuation from a line of an ini-file, and initializes 3 pointers
you supply with its section-name, key-name and value string tokens.

uCiniParse()
------------
You supply a filename and a mapping datastructure address, it reads all
data specified in the file into your internal format.
Keys specified in the mapping but not mentioned in the ini-file will be
left unchanged, thus giving you the possiblity to use a default value.

uCiniDump()
-----------
Writes all mapped data into the ini-file you specify.

sscand()
--------
Lightweight function to read decimal number into internal binary format.

scatd()
-------
Lightweight function to append an integer to a string in decimal format.

MAPPING
=======

Create an ini-file, similar to the ones read, with mapping data specified
as comments (following a semicolon). The format is as follows:

[section]
key=;identifier;type

The following types are supported:
u1 s1	unsigned / signed 1-byte integer
u2 s2	unsigned / signed 2-byte integer
u4 s4	unsigned / signed 4-byte integer
bx	1-bit flag in char, position x (0..7)
bxy     x-bit (1..7) field in char, position y (0..7)
sym	symbol without address, like bitfield, access function auto-generated
fun	user defined access function, name supplied in identifier

Access function signature:
static void <name>(char *str, int write);
When write is zero, your function shall convert the value supplied as str
into your internal representation.
When write is nonzero, your function shall save your internal data into
zero-terminated string str.
