tss2-tctildr - Simplifiy management of TCTI instance lifecycle.

This library simplifies the instantiation and finalization of TCTI instances.

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”.
