typedef struct SilcIDCacheEntryStruct { ... } SilcIDCacheEntry;

    This is an entry in the SILC ID Cache system.  This context is
    allocated by adding new entry to ID cache by calling silc_idcache_add.
    Each of the fields in the structure are allocated by the caller.

    typedef struct SilcIDCacheEntryStruct {
      struct SilcIDCacheEntryStruct *next;
      void *id;                            /* Associated ID */
      char *name;                          /* Associated entry name */
      void *context;                       /* Associated context */
    } *SilcIDCacheEntry;
