memory release problem of memcached_get

[然 安]

HI,all:
    When the function memcached_get() is used to retrieve data from memcached 
servers, we need't to allocate memory for the returned value and  only transmit 
a pointer to it. I want to know when  this automatically allocated memory will 
be released? At the end of the function memcached_get is called? thank you for 
your reply.
