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);
	 }
