  27. One-Call function for TPM2_FlushContext
  28. .PP
  29. This function invokes the TPM2_FlushContext 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\&.

  62. Asynchronous function for TPM2_FlushContext
  63. .PP
  64. This function invokes the TPM2_FlushContext 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_FlushContext_Finish\&.

  91. This function returns the results of a TPM2_FlushContext command invoked via Esys_FlushContext_Finish\&. All non-simple output parameters are allocated by the function's implementation\&. NULL can be passed for every output parameter if the value is not required\&.
