.SH NAME
ne_buffer_destroy, ne_buffer_finish \- destroy a buffer object
.SH "SYNOPSIS"

#include <ne_string\&.h>

.HP 24
void\ \fBne_buffer_destroy\fR\ (ne_buffer\ *\fIbuf\fR);

.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:

.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
