buffer_peek(3)        DragonFly Library Functions Manual        buffer_peek(3)

NAME
       buffer_peek - return pointer to string in buffer

SYNTAX
       #include <buffer.h>

       int buffer_peek(buffer* b);

DESCRIPTION
       buffer_peek returns a pointer to the first byte of the string in the
       buffer.

EXAMPLE
       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);
         }
