◆ tpm_marshal_command()

int tpm_marshal_command	(	TPM_CC	command,
		const void *	tpm_command_body,

	)

tpm_marshal_command

Given a structure containing a TPM2 command, serialize the structure for sending it to the TPM.

@command: code of the TPM2 command to marshal @tpm_command_body: a pointer to the command specific structure @ob: output buffer where command is marshaled to

Returns 0 on success or -1 on error.

◆ tpm_unmarshal_response()

struct tpm2_response* tpm_unmarshal_response	(	TPM_CC	command,
		struct ibuf *	ib
	)

tpm_unmarshal_response

Given a buffer received from the TPM in response to a certain command, deserialize the buffer into the expected response structure.

struct tpm2_response is a union of all possible responses.

@command: code of the TPM2 command for which a response is unmarshaled @ib: input buffer containing the serialized response.

Returns a pointer to the deserialized response or NULL in case of unmarshaling problems.
