Tspi_TPM_DirWrite(3) Library Functions Manual Tspi_TPM_DirWrite(3) TCG Software Stack Developer's Reference NAME Tspi_TPM_DirWrite - write to a Data Integrity Register SYNOPSIS #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_DirWrite(TSS_HTPM hTPM, UINT32 ulDirIndex, UINT32 ulDirDataLength, BYTE* rgbDirData); DESCRIPTION Tspi_TPM_DirWrite writes a data integrity register. You need to know the DIR index and data you wish to write to the DIR prior to using this com- mand. PARAMETERS hTPM The hTPM parameter is used to specify the handle of the TPM object. ulDirIndex The ulDirIndex parameter is the index of the DIR to write. To query the TPM for the number of DIR registers it supports, use Tspi_TPM_GetCapability(3). ulDirDataLength The ulDirDataLength parameter is the length in bytes of the rgbDirData pa- rameter. rgbDirData The rgbDirData parameter is a pointer to memory containing the data to be written to the DIR. RETURN CODES Tspi_TPM_DirWrite returns TSS_SUCCESS on success, otherwise one of the fol- lowing 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. CONFORMING TO Tspi_TPM_DirWrite conforms to the Trusted Computing Group Software Specifi- cation version 1.1 Golden SEE ALSO Tspi_TPM_GetCapability(3), Tspi_TPM_DirRead(3).
