# buffer\_peek(3diet)

return pointer to string in buffer

## 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);\
   }
