## DESCRIPTION

The krb5\_rcache structure holds a storage element that is used for data manipulation. The structure contains no public accessible elements.

**krb5\_rc\_initialize**() Creates the reply cache *id* and sets it lifespan to *auth\_lifespan*. If the cache already exists, the content is destroyed.
