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.
