Tspi_TPM_SetStatus - modify the TPM's status

 #include <tss/platform.h>  #include <tss/tcpa_defines.h>  #include <tss/tcpa_typedef.h>  #include <tss/tcpa_struct.h>  #include <tss/tss_typedef.h>  #include <tss/tss_structs.h>  #include <tss/tspi.h>  "TSS_RESULT Tspi_TPM_SetStatus(TSS_HTPM " hTPM ", TSS_FLAG " statusFlag ","  " TSS_BOOL " fTpmState ");" 

Tspi_TPM_SetStatus alters the status of the TPM. Depending on the chosen statusFlag, fTpmState may or may not be ignored. This command requires that the TPM be on and the handle to the TPM available. This command is not currently implemented.

The hTPM parameter is used to specify the handle of the TPM object. The statusFlag parameter is what the TPM status should be set to. The fTpmState parameter is the status value to set. For some states, this flag is ignored.

Tspi_TPM_SetStatus returns TSS_SUCCESS on success, otherwise one of the following values is returned:

TSS_E_INVALID_HANDLE hTPM is not a valid handle.

TSS_E_INTERNAL_ERROR An internal SW error has been detected.

TSS_E_BAD_PARAMETER One or more parameters is bad.

Tspi_TPM_SetStatus conforms to the Trusted Computing Group Software Specification version 1.1 Golden

Tspi_TPM_GetStatus(3), Tspi_TPM_GetCapability(3).
