HITLS_GetSharedGroup() int32_t HITLS_GetSharedGroup ( const HITLS_Ctx *  ctx, int32_t  nmatch, uint16_t *  groupId  ) Obtain the supported peer group or the number of supported peer groups of the nth match. nmatch Value range: - 1 or a positive integer This function can be called only after negotiation and can be called only by the server. If nmatch is a positive integer, check the intersection of groups on the client and server, and return the nmatch group in the intersection by groupId. If the value of nmatch is - 1, the number of intersection groups on the client and server is returned based on groupId. 参数 ctx [IN] TLS connection handle. nmatch [IN] Sequence number of the group to be obtained, -1 Return the number of supported peer groups. groupId [OUT] Returned result. 返回值 HITLS_SUCCESS,Obtaining the status succeeded.
