buffer_peek - return pointer to string in buffer
#include <libowfat/buffer.h>
char* buffer_peek(buffer* b);
buffer_peek returns a pointer to the first byte of the string in the buffer.
buffer_feed, buffer_peek and buffer_seek can be used for efficient reading loops, nearly the same speed as calling op directly:
for (;;) {
r = buffer_feed(&b);
if (r <= 0) return r;
x = buffer_peek(&b);
dosomething(x,r);
buffer_seek(&b,r);
}
