Circular byte buffer
This is a circular buffer implementation, useful for embedded systems (buffer for UART RX queue etc).
Usage
#include <stdint.h>
uint8_t buffer[32]; // array backing the buffer
CircularBuffer cb; // buffer instance
void main()
{
cbuf_init(&cb, buffer, 32); // init the buffer
// now it's ready for use!
}
Many function return success flag, so make sure to check the return values.
False is returned on buffer overflow / underflow, attempted read past available data size etc. See the header file for details.
