buffer_peek(3) 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);
}
