Tspi_Hash_GetHashValue(3) Library Functions Manual Tspi_Hash_GetHashValue(3) TCG Software Stack Developer's Reference NAME Tspi_Hash_GetHashValue - get the current hash value of a hash object 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_Hash_GetHashValue(TSS_HHASH hHash, UINT32* pulHashValueLength, BYTE** prgbHashValue); DESCRIPTION Tspi_Hash_GetHashValue gets the hash value of a hash object. Tspi_Con- text_FreeMemory must be used to clean up after this function, as memory is allocated for the prgbHashValue data. PARAMETERS hHash The handle to the hash object instance whose hash value should be signed. pulHashValueLength Receives the length of the hash value data returned at the parameter prgb- HashValue. prgbHashValue Receives a pointer to the hash value data. RETURN CODES Tspi_Hash_GetHashValue returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hHash 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. TSS_E_HASH_INVALID_LENGTH Hash length is inconsistent with hash algorithm. TSS_E_HASH_NO_DATA Hash object has no internal hash value.
