NAME
memcached_delete - Delete a key
LIBRARY
C Client Library for memcached (libmemcached, -lmemcached)
SYNOPSIS
#include <memcached.h>
memcached_return_t
memcached_delete (memcached_st *ptr,
const char *key, size_t key_length,
time_t expiration);
memcached_return_t
memcached_delete_by_key (memcached_st *ptr,
const char *master_key, size_t master_key_length,
const char *key, size_t key_length,
time_t expiration);
DESCRIPTION
memcached_delete() is used to delete a particular key.
memcached_delete_by_key() works the same, but it takes a master key to
find the given value.
Expiration works by placing the item into a delete queue, which means
that it won’t possible to retrieve it by the "get" command, but "add"
and "replace" command with this key will also fail (the "set" command
will succeed, however). After the time passes, the item is finally
deleted from server memory.
Please note the the Danga memcached server removed support for
expiration in the 1.4 version.
RETURN
A value of type "memcached_return_t" is returned On success that value
will be "MEMCACHED_SUCCESS". Use memcached_strerror() to translate
this value to a printable string.
If you are using the non-blocking mode of the library, success only
means that the message was queued for delivery.
