NAME
buffer_peek - return pointer to string in bufferSYNTAX
#include <libowfat/buffer.h>char* 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); }
