.SH "NAME"
ne_buffer_destroy, ne_buffer_finish \- destroy a buffer object
.SH "SYNOPSIS"
.sp
.ft B
.nf
#include <ne_string\&.h>
.fi
.ft
.HP \w'void\ ne_buffer_destroy('u
.BI "void ne_buffer_destroy(ne_buffer\ *" "buf" ");"
.HP \w'char\ *ne_buffer_finish('u
.BI "char *ne_buffer_finish(ne_buffer\ *" "buf" ");"
.SH "DESCRIPTION"
.PP
\fBne_buffer_destroy\fR
frees all memory associated with the buffer\&.
\fBne_buffer_finish\fR
frees the buffer structure, but not the actual string stored in the buffer, which is returned and must be
\fBfree\fR()d by the caller\&.
.PP
Any use of the buffer object after calling either of these functions gives undefined behaviour\&.
.SH "RETURN VALUE"
.PP
\fBne_buffer_finish\fR
returns the
\fBmalloc\fR\-allocated string stored in the buffer\&.
.SH "EXAMPLES"
.PP
An example use of
\fBne_buffer_finish\fR; the
\fBduplicate\fR
function returns a string made up of
\fIn\fR
copies of
\fIstr\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
static char *duplicate(int n, const char *str)
{
  ne_buffer *buf = ne_buffer_create();
  while (n\-\-) {
    ne_buffer_zappend(buf, str);
  }
  return ne_buffer_finish(buf);
}
.fi
.if n \{\
