• ringbuffer_pop()
• ringbuffer_push()
• ringbuffer_peek()
• ringbuffer_reset()

• RINGBUFFER_DEFINE() - create and initialize buffer
• RINGBUFFER_EMPTY() - if empty then return non zero value
• RINGBUFFER_FULL() - if full then return non zero value
• RINGBUFFER_CURR_SIZE() - number of items in the buffer
• RINGBUFFER_MAXSIZE() - max size of the buffer
• RINGBUFFER_FREE_SIZE() - free size of the buffer

Defined macro RINGBUFFER_DEFINE(buffer, size), the macro creates a static array of defined size and init necessary values.

How to work with buffer and implemented operations can be found in ringbuffer_test.c

The program has been compiled and tested under linux system.

It's written for C99 support.

Requirements: gcc, make

How to compile: $ make

After this the "ringbuffer_test" executable file will be created.

Test 1 (Buffer init) ... pass.
Test 2 (Push one item and pop it) ... pass.
Test 3 (Fill buffer with test data) ... pass.
Test 4 (Test reset buffer) ... pass.
Test 5 (Test current size) ... pass.
Test 6 (Fill buffer to full and empty it then) ... pass.
Test 7 (Reset buffer and fill again) ... pass.
Test 8 (Test peek) ... pass.
Test 9 (Test buffer size 0) ... pass.
