.TH buffer_peek 3
|
|
.SH NAME
|
|
buffer_peek \- return pointer to string in buffer
|
|
.SH SYNTAX
|
|
.B #include <libowfat/buffer.h>
|
|
|
|
char* \fBbuffer_peek\fP(buffer* \fIb\fR);
|
|
.SH DESCRIPTION
|
|
buffer_peek returns a pointer to the first byte of the string in the
|
|
buffer.
|
|
.SH EXAMPLE
|
|
buffer_feed, buffer_peek and buffer_seek can be used for efficient reading
|
|
loops, nearly the same speed as calling \fBop\fR directly:
|
|
|
|
for (;;) {
|
|
r = buffer_feed(&b);
|
|
if (r <= 0) return r;
|
|
x = buffer_peek(&b);
|
|
dosomething(x,r);
|
|
buffer_seek(&b,r);
|
|
}
|
|
