buffer_peek - Man Page

#include <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);
 }
