One-Call function for TPM2_Rewrap
.PP
This function invokes the TPM2_Rewrap command in a one-call variant\&. This means the function will block until the TPM response is available\&. All input parameters are const\&. The memory for non-simple output parameters is allocated by the function implementation\&.

Asynchronous function for TPM2_Rewrap
.PP
This function invokes the TPM2_Rewrap command in a asynchronous variant\&. This means the function will return as soon as the command has been sent downwards the stack to the TPM\&. All input parameters are const\&. In order to retrieve the TPM's response call Esys_Rewrap_Finish\&.
