/**
 * gnutls_priority_get_cipher_suite:
 * @pcache: is a #gnutls_prioritity_t type.
 * @idx: is an index number.
 * @sidx: internal index of cipher suite to get information about.
 *
 * Provides the internal ciphersuite index to be used with
 * gnutls_cipher_suite_info(). The index @idx provided is an 
 * index kept at the priorities structure. It might be that a valid
 * priorities index does not correspond to a ciphersuite and in 
 * that case %GNUTLS_E_UNKNOWN_CIPHER_SUITE will be returned. 
 * Once the last available index is crossed then 
 * %GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
 *
 * Returns: On success it returns %GNUTLS_E_SUCCESS (0), or a negative error value otherwise.
