Description

TSVConnClientHelloGet() retrieves ClientHello message data from the TLS virtual connection sslp. Returns a TSClientHello always. The availability of the returned object must be checked before use.

Important

This function should only be called from the TS_EVENT_SSL_CLIENT_HELLO hook. The returned TSClientHello is only valid during the SSL ClientHello event processing. Using this function from other hooks may result in accessing invalid or stale data.

TSClientHelloExtensionGet() retrieves extension data for the specified type (e.g., 0x10 for ALPN). Returns TS_SUCCESS if found, TS_ERROR otherwise. The returned pointer in out is valid only while ch exists.
