ConfLib is a library which deals with Conf files : you can insert or get any value (long integer or string) in TEXT files.


**** There are 5 available functions ****
long value = conflib::get_num_key(const char *file, const char *section, const char *key, long default, const short *error)
short error = conflib::add_num_key(const char *file, const char *section, const char *key, long value)
short error = conflib::remove_key(const char *file, const char *section, const char *key)
short error = conflib::get_string_key(const char *file, const char *section, const char *key, const char *value, long max_length, const char *default)
short error = conflib::add_string_key(const char *file, const char *section, const char *key, const char *value)

the different values for error are self-explained : 
CONFLIB_OK equ 0
CONFLIB_FILE_NOT_FOUND equ 1
CONFLIB_KEY_NOT_FOUND equ 2
CONFLIB_INVALID_KEY equ 3
CONFLIB_UNSAVED_FILE equ 4
CONFLIB_UNARCHIVED_FILE equ 5
CONFLIB_CANT_CREATE_FILE equ 6
CONFLIB_SECTION_NOT_FOUND equ 7


file is a TEXT file which must be located in the SYSTEM folder defined by the kernel ('main' by default)
If it already exists but it isn't a TEXT, ConfLib will return CONFLIB_FILE_NOT_FOUND
It it doesn't exist, ConfLib will create it.
It ConfLib writes in this file and it was archived, it will be re-archived after a succesful write.
Don't specify the folder (i.e. don't type conflib::get_num_key("folder\file", ... but conflib::get_num_key("file", ...)
Perhaps I will change this (the searched folder will be the system folder only if it isn't specified)



For a more precise description of the avalaible functions, please take a look on the ConfLib.h header files.

**** Note for assembly programmers **** 
All the registers except d0.l are preserved
Parameters are pushed on the stack, like traditional C functions

**** Format of the text file ****
* comments are accepted : a line is a comment if it begins by a '#' character
* spaces are accepted in front of a key and around the '=' sign, but NOT at the end of a line
* strings are delimited by '"' characters
any valid variable name begins by _, a-z or A-Z and contains only characters among _, a-z, A-Z and 0-9. Its length is arbitrary.
any valid section name begins by _, a-z or A-Z and contains only characters among _, a-z, A-Z and 0-9 and its length is inferior or equal to 16 chars.

exemple of correct conf file :
-----------------------------------------------------------


#comment 1
key_1 = 45312
key_2= 545
key_4   =0121647
[section_1]
another_key = "string"
  #another comment
[section_2]
key_1 = "Hello, world"
key_2 = "I'm Flanker"

conflib::get_num_key("file","section_1","another_key",12,&error) will return 12 and error = CONFLIB_INVALID_KEY
conflib::get_num_key("file","","key_1",12,&error) will return 45312 and error = CONFLIB_OK
conflib::get_string_key("file","section_2","key_1",*value,10,*default) will return CONFLIB_OK and value = "Hello, world"




-----------------------------------------------------------

examples of incorrect files :

(spaces after the key value)
-----------------------------------------------------------
 key = 755545      
-----------------------------------------------------------

(comment after a key)
-----------------------------------------------------------
 key = 5451212#comment
-----------------------------------------------------------


("" character int he middle of a string)
-----------------------------------------------------------
key="strings"strings"
