\fBReturn values:\fP
.RS 4
\fITSS2_RC_SUCCESS\fP if the function call was a success\&. 
.br
\fITSS2_FAPI_RC_BAD_REFERENCE\fP if context or path is NULL\&. 
.br
\fITSS2_FAPI_RC_BAD_CONTEXT\fP if context corruption is detected\&.

\fITSS2_FAPI_RC_MEMORY\fP if the FAPI cannot allocate enough memory for internal operations or return parameters\&. 
.br
\fITSS2_FAPI_RC_NO_TPM\fP if FAPI was initialized in no-TPM-mode via its config file\&. 
.br
\fITSS2_FAPI_RC_PATH_NOT_FOUND\fP if a FAPI object path was not found during authorization\&. 
.br
\fITSS2_FAPI_RC_KEY_NOT_FOUND\fP if a key was not found\&.

.SS "Fapi_GetEsysBlob_Finish (\fBFAPI_CONTEXT\fP * context, uint8_t * type, uint8_t ** data, size_t * length)"
Asynchronous finish function for Fapi_GetEsysBlob
.PP
This function should be called after a previous Fapi_GetEsysBlob_Async\&.
.PP
\fBParameters:\fP
.RS 4
\fIcontext\fP The \fBFAPI_CONTEXT\fP 
.br
\fItype\fP The type of the returned blob\&.

\fBReturn values:\fP
.RS 4
\fITSS2_RC_SUCCESS\fP if the function call was a success\&.

\fITSS2_FAPI_RC_BAD_CONTEXT\fP if context corruption is detected\&. 
.br
\fITSS2_FAPI_RC_BAD_SEQUENCE\fP if the context has an asynchronous operation already pending\&. 
.br
\fITSS2_FAPI_RC_IO_ERROR\fP if the data cannot be saved\&. 
.br
\fITSS2_FAPI_RC_MEMORY\fP if the FAPI cannot allocate enough memory for internal operations or return parameters\&. 
.br
\fITSS2_FAPI_RC_TRY_AGAIN\fP if the asynchronous operation is not yet complete\&. Call this function again later\&. 
.br
\fITSS2_FAPI_RC_GENERAL_FAILURE\fP if an internal error occurred\&.
