NAME

       memcached_delete - libmemcached Documentation

SYNOPSIS

       #include <libmemcached/memcached.h>
              Compile and link with -lmemcached

       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   *group_key,
       size_t group_key_length, const char *key, size_t key_length, time_t expiration)

              Parametersptr -- pointer to initialized memcached_st struct

                     • group_key -- key namespace

                     • group_key_length -- length of the group_key without any terminating zero

                     • key -- the key to delete

                     • key_length -- the length og the key without any terminating zero

                     • expiration -- obsolete since memcached(1) version 1.4

              Returns
                     memcached_return_t indicating success

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  be
       possible  to  retrieve it by the "get" command. The "add" and "replace" commands 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 memcached server removed tests for expiration in the 1.4 version.

RETURN VALUE

       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.
