/*
|
||||
* This file implements stretchy buffers as invented (?) by Sean Barrett.
|
||||
* Based on the implementation from the public domain Bitwise project
|
||||
* by Per Vognsen - https://github.com/pervognsen/bitwise
|
||||
*
|
||||
* It's a super simple type safe dynamic array for C with no need
|
||||
* to predeclare any type or anything.
|
||||
* The first time an element is added, memory for 16 elements are allocated.
|
||||
* Then every time length is about to exceed capacity, capacity is doubled.
|
||||
*
|
||||
* Sample usage:
|
||||
*
|
||||
* mytype_t* buf = NULL;
|
||||
* RBUF_PUSH(buf, some_element);
|
||||
* RBUF_PUSH(buf, other_element);
|
||||
* -- now RBUF_LEN(buf) == 2, buf[0] == some_element, buf[1] == other_element
|
||||
*
|
||||
* -- Free allocated memory:
|
||||
* RBUF_FREE(buf);
|
||||
* -- now buf == NULL, RBUF_LEN(buf) == 0, RBUF_CAP(buf) == 0
|
||||
*
|
||||
* -- Explicitly increase allocated memory and set capacity:
|
||||
* RBUF_FIT(buf, 100);
|
||||
* -- now RBUF_LEN(buf) == 0, RBUF_CAP(buf) == 100
|
||||
*
|
||||
* -- Resize buffer (does not initialize or zero memory!)
|
||||
* RBUF_RESIZE(buf, 200);
|
||||
* -- now RBUF_LEN(buf) == 200, RBUF_CAP(buf) == 200
|
||||
*
|
||||
* -- To handle running out of memory:
|
||||
* bool ran_out_of_memory = !RBUF_TRYFIT(buf, 1000);
|
||||
* -- before RESIZE or PUSH. When out of memory, buf will stay unmodified.
