buffer_peek (3)

#include <buffer.h>

int 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);
  }
