ini2buff

Parse INI format data in buffer. A very simple and easy to use util.

Receive INI format data from server, it can direct to parse in buffer, modify, then send back to server, is not nessisary save to local file.

How to use ini2buff:

1. Load your ini file to buffer:

   char* inibuf = load2buffer("test.ini");

   or receive your ini format data from network

   char* inibuf = ...

2. Operation on your ini format data:

   1. Get value of key

   char* value = get_inival(inibuf, "common", "testkey");

   3. Set value of key (if section or key not exist, will create it)

   set_inival(inibuf, "common", "server_port", "54321");

   5. Del key and value

   del_key(inibuf, "device", "config_api");

   7. Del the whole setion

   del_section(inibuf, "device");

3. Write ini format data in buffer to file

   size_t rs = write2file("test.ini", inibuf);

4. Free buffer of the ini format data

   free_all();

5. How to build the test file (test/test_main.c)

   cd test/

   gcc -c test_main.c ../ini2buff.c ../utils_string.c

   gcc test_main.o ini2buff.o utils_string.o -o test

   ./test
