# TSProtoSet(3ts)

TSProtoSet API function

## NAME

TSProtoSet - TSProtoSet API function

## SYNOPSIS

*#include \<ts/ts.h\>*

- **TSNextProtocolSet TSGetcloneProtoSet(TSAcceptor *tna*)**

  - **TSNextProtocolSet TSUnregisterProtocol(TSNextProtocolSet *protoset*, const char \**protocol*)**

  - **void TSRegisterProtocolSet(TSVConn *sslp*, TSNextProtocolSet *ps*)**

  ## DESCRIPTION

*TSGetcloneProtoSet()* makes a copy of the ProtocolSet to be advertised by the ssl connection associated with *tna*. This function returns **TSNextProtocolSet** object which points to a clone of the protocolset owned by *tna*. This type represents the protocolset containing the protocols which are advertised by an ssl connection during ssl handshake. Each **TSAcceptor** object is associated with a protocolset.

*TSUnregisterProtocol()* unregisters *protocol* from *protoset* and returns the protocol set. The returned protocol set needs to be registered with the **TSVConn** using *TSRegisterProtocolSet()* that will advertise the protocols.

*TSRegisterProtocolSet()* registers *ps* with *sslp*. This function clears the protocolset string created by the already registered protocolset before registering the new protocolset. On Success, the ssl object associated with *sslp* will then advertise the protocols contained in *ps*.
