# tss2-tctildr(7)

Simplifiy management of TCTI instance lifecycle.

## NAME

tss2-tctildr - Simplifiy management of TCTI instance lifecycle.

## SYNOPSIS

This library simplifies the instantiation and finalization of TCTI instances.

## DESCRIPTION

The TCTI dynamic loading and initialization protocol requires a lot of boilerplate code. To reduce duplication the tss2-tctildr library adds the **Tss2\_TctiLdr\_Initialize**(), **Tss2\_TctiLdr\_Initialize\_Ex**(), and **Tss2\_TctiLdr\_Finalize**() functions to abstract away the machinery required to load, initialize, and finalize a TCTI context.

To assist in the discovery of TCTIs this library provides the **Tss2\_TctiLdr\_GetInfo**() function. This function, paired with a ‘free’ function to free the memory allocated by ‘GetInfo’, provides a simple query interface for discovery of the available and default TCTIs available to the tss2-tctildr implementation

The interface exposed by this library is defined in the “TSS System Level API and TPM Command Transmission Interface Specification”.
