/**
 * membuf - simple linear memory buffer routines.
 *
 * It's common to want a linear memory buffer, where you can get memory on
 * the end, and consume memory from the start.  The details of actually
 * when to enlarge or move the buffer are slightly nontrivial, so they're
 * encapsulated here.

 * Example:
 * #include <ccan/membuf/membuf.h>
 * #include <string.h>
 * #include <stdio.h>
 *
 * // Given "hello world" outputs helloworld
 * // Given "hello there world" outputs hellothereworld
 * int main(int argc, char *argv[])
 * {
 *	MEMBUF(char) charbuf;
 *
 *	membuf_init(&charbuf, malloc(10), 10, membuf_realloc);
 *
 *	for (int i = 1; i < argc; i++) {
 *		size_t len = strlen(argv[i]);
 *		memcpy(membuf_add(&charbuf, len), argv[i], len);
 *	}
 *
 *	// This is dumb, we could do all at once, but shows technique.
 *	while (membuf_num_elems(&charbuf) > 0)
 *		printf("%c", *(char *)membuf_consume(&charbuf, 1));
 *	printf("\n");
 *	free(membuf_cleanup(&charbuf));
 *	return 0;
 * }
