ringbb

Ring Byte Buffer in pure C, auto resizable, no thread safe, and with the capability to push(write) the pop(read) data buffer in both sides. It could then be used flexibly in different scenarios and with C and C++ respectively.

Interface

bool rbb_init(ringbb*, size_t);
void rbb_free(ringbb*);
bool rbb_shrink(ringbb*);
bool rbb_push_back(ringbb*, const void*, size_t);
bool rbb_push_front(ringbb*, const void*, size_t);
size_t rbb_pop_front(ringbb*, void*, size_t);
size_t rbb_pop_back(ringbb*, void*, size_t);

To access ring byte buffer's capacity and size, just visit the member variable. Suppose rb is a pointer to ringbb struct (check ring_byte_buf.h), capacity is rb->capacity, size is rb->size. You can only read them, do not modify them in any case!!

Test on Linux

$ make
$ ./testc
$ ./cpptest

If no FAILED literal, it's passed!

Example

test_ringbb.c and cpptest.cpp can be taken as examples.
