.SH "DESCRIPTION"
.PP
The
\fBne_buffer_clear\fR
function sets the string stored in
\fIbuf\fR
to be the empty string ("")\&.
.PP
The
\fBne_buffer_altered\fR
function must be used after the string stored in the buffer
\fIbuf\fR
is modified by directly rather than using
ne_buffer_append,
ne_buffer_zappend
or
ne_buffer_concat\&.
.PP
The
\fBne_buffer_grow\fR
function ensures that at least
\fIsize\fR
bytes are allocated for the string; this can be used if a large amount of data is going to be appended to the buffer and may result in more efficient memory allocation\&.
