The Thread Control Structure (TCS) contains meta-data used by the hardware to save and restore thread specific information when entering/exiting the enclave. A TCS can be added to an initialized enclave by first adding a new regular enclave page, initializing the content of the new page from within the enclave, and then changing that page's type to a TCS. Support the initialization of a TCS from within the enclave. The variable information needed that should be provided from outside the enclave is the address of the TCS, address of the State Save Area (SSA), and the entry point that the thread should use to enter the enclave. With this information provided all needed fields of a TCS can be initialized.
