typedef struct SilcClientStruct { ... } *SilcClient

    This is the actual SILC Client structure which represents one
    SILC Client.  It is allocated with the silc_client_alloc function
    and given as argument to all SILC Client Library functions.  It
    is initialized with silc_client_init function, and freed with
    silc_client_free function.
