Tspi_TPM_DirRead(3) Library Functions Manual Tspi_TPM_DirRead(3) TCG Software Stack Developer's Reference NAME Tspi_TPM_DirRead - Read 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_DirRead(TSS_HTPM hTPM, UINT32 ulDirIndex, UINT32* pulDirDataLength, BYTE** prgbDirData); DESCRIPTION Tspi_TPM_DirRead reads a data integrity register. DIRs are non-volatile (persistent across reboots) memory areas maintained by the TPM. 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 read. To query the TPM for the number of DIR registers it supports, use Tspi_TPM_GetCapa- bility(3). pulDirDataLength The pulDirDataLength parameter receives the length in bytes of the prgbDirData parameter. prgbDirData The prgbDirData parameter receives a pointer to memory containing the DIR data. RETURN CODES Tspi_TPM_DirRead 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. CONFORMING TO Tspi_TPM_DirRead conforms to the Trusted Computing Group Software Spec- ification version 1.1 Golden SEE ALSO Tspi_TPM_GetCapability(3), Tspi_TPM_DirWrite(3).
