Asynchronous function for TPM2_Clear
.PP
This function invokes the TPM2_Clear 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_Clear_Finish\&.

\fBReturn values\fP
.RS 4
\fIESYS_RC_SUCCESS\fP if the function call was a success\&. 
.br
\fITSS2_ESYS_RC_BAD_REFERENCE\fP if the esysContext or required input pointers or required output handle references are NULL\&. 
.br
\fITSS2_ESYS_RC_BAD_CONTEXT\fP if esysContext corruption is detected\&. 
.br
\fITSS2_ESYS_RC_MEMORY\fP if the ESAPI cannot allocate enough memory for internal operations or return parameters\&. 
.br
\fITSS2_RCs\fP produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally\&.

\fITSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS\fP if more than one session has the 'decrypt' attribute bit set\&. 
.br
\fITSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS\fP if more than one session has the 'encrypt' attribute bit set\&. 
.br
\fITSS2_ESYS_RC_BAD_TR\fP if any of the ESYS_TR objects are unknown to the \fBESYS_CONTEXT\fP or are of the wrong type or if required ESYS_TR objects are ESYS_TR_NONE\&. 
.br
\fITSS2_ESYS_RC_NO_DECRYPT_PARAM\fP if one of the sessions has the 'decrypt' attribute set and the command does not support encryption of the first command parameter\&.
