NE_BUFFER_DESTROY

Section: neon API reference (3)
Updated: 30 September 2016
Index Return to Main Contents

NAME

ne_buffer_destroy, ne_buffer_finish - destroy a buffer object

SYNOPSIS

#include <ne_string.h>

void ne_buffer_destroy(ne_buffer *buf);
char *ne_buffer_finish(ne_buffer *buf);

DESCRIPTION

ne_buffer_destroy

frees all memory associated with the buffer. ne_buffer_finish frees the buffer structure, but not the actual string stored in the buffer, which is returned and must be free()d by the caller.

Any use of the buffer object after calling either of these functions gives undefined behaviour.

RETURN VALUE

ne_buffer_finish returns the malloc-allocated string stored in the buffer.

EXAMPLES

An example use of ne_buffer_finish; the duplicate function returns a string made up of n copies of str:

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);
}
