Concering this post I have extended the scripts!

First of all I'm not be able to read out the whole ini file via windows commands.
But MrGuest wrote a "work around".

Here are the scripts:

config.c
Code:

////////////////////////////////////////////////////////////////////////////////////////////////////
// read the whole ini file
////////////////////////////////////////////////////////////////////////////////////////////////////

STRING* str_file_data = "";
var _fHandle_user_config_i = NULL;

void get_user_settings(STRING* local_filename) 
{
	_fHandle_user_config_i = file_open_read(local_filename);
	
	if(_fHandle_user_config_i){ //read config file
		int eof = 0;
		while(eof != -1){
			eof = file_str_read(_fHandle_user_config_i, str_file_data);
			var_for_name(str_file_data);
		}
	}
	file_close(_fHandle_user_config_i);
}

////////////////////////////////////////////////////////////////////////////////////////////////////
// read single/predefinded variables
////////////////////////////////////////////////////////////////////////////////////////////////////

//predefinded variables
char result_chr[32];
int version_;

void read_ini(STRING* local_filename)
{
	STRING* path_to_ini = "#256";

	//set path
	str_cpy(path_to_ini,work_dir);
	str_cat(path_to_ini,"\\");
	str_cat(path_to_ini,local_filename);

	// section, key, default value, predefined string,size, file
	GetPrivateProfileString("header", "game_name", "can't read string", result_chr, 32, _chr(path_to_ini));

	// var = section, key, default value, file
	version_ = GetPrivateProfileInt("header", "version", 0, _chr(path_to_ini));
}

////////////////////////////////////////////////////////////////////////////////////////////////////
// write single/predefinded variables
////////////////////////////////////////////////////////////////////////////////////////////////////

void write_ini(STRING* local_filename, STRING* section, STRING* variable)
{
	STRING* path_to_ini = "#256";
	STRING* variable_value = "#32";

	str_cpy(path_to_ini,work_dir);
	str_cat(path_to_ini,"\\");
	str_cat(path_to_ini,local_filename);

	str_cpy(variable_value,variable);
	var_for_name(variable_value);
	str_clip(variable_value,(str_len(variable)+3));

	WritePrivateProfileString(section, variable, _chr(variable_value), _chr(path_to_ini));
}


main script
Code:
snd_vol_menu=50;
//ini file, section, variable
write_ini("config.ini", "soundsettings", "snd_vol_menu");


config.ini
Code:
[soundsettings]

snd_vol_bomb=500
snd_vol_crate=250
snd_vol_song=0
snd_vol_menu=0
