libmemcache mc_get() Usage

[Mdecandia]

Hi all,
I'm trying to use libmemcache C api to send and retrieve buffers from
memcached.
I've seen that mc_get() function need a memcache_req structure to retrieve
data from
cache but I need to know the size of item to retrieve. Is this right?
I don't know that size so I've used mc_aget2() function.
I'm forced to use this one or there is some method to use mc_get unknowning 
the size of item to retrieve?

Thanks,
Michele
