+ * rbuf - buffered I/O input primitive.
+ *
+ * This code is like stdio, only simpler and more transparent to the user.

+ *
+ * Example:
+ *	#include <ccan/rbuf/rbuf.h>
+ *	#include <ccan/err/err.h>
+ *	#include <stdlib.h>
+ *	#include <unistd.h>
+ *
+ *	// Dumb demo program to replace ' ' with '*'.
+ *	int main(int argc, char *argv[])
+ *	{
+ *		struct rbuf in;
+ *		char *word;
+ *
+ *		if (argv[1]) {
+ *			if (!rbuf_open(&in, argv[1], NULL, 0))
+ *				err(1, "Failed opening %s", argv[1]);
+ *		} else
+ *			rbuf_init(&in, STDIN_FILENO, NULL, 0);
+ *
+ *		while ((word = rbuf_read_str(&in, ' ', realloc)) != NULL)
+ *			printf("%s*", word);
+ *
+ *		if (errno)
+ *			err(1, "Reading %s", argv[1] ? argv[1] : "<stdin>");
+ *
+ *		// Free the buffer, just because we can.
+ *		free(in.buf);
+ *		return 0;
