TPMLIB_DecodeBlob(3)					    TPMLIB_DecodeBlob(3)

NAME
     TPMLIB_DecodeBlob	  - Decode a base64-encode TPM blob

SYNOPSIS
     #include <libtpms/tpm_types.h>

     #include <libtpms/tpm_library.h>

     TPM_RESULT TPMLIB_DecodeBlob(const char *buffer,
				  enum TPMLIB_BlobType type,
				  unsigned char **result
				  size_t *result_len);

DESCRIPTION
     The TPMLIB_DecodeBlob() function is used to decode a base64-encoded TPM
     state blob. The caller must pass what type of blob is expected to be de-
     coded and following that the function will look for the start and end mark-
     ers of the data.

     The following types of blobs are supported along with their start and end
     markers:

     BLOB_TYPE_INITSTATE
	 '-----BEGIN INITSTATE-----' marks the beginning of the base64-encoded
	 blob.

	 '-----END INITSTATE-----' marks the end of the base64-encoded blob.

     This function is useful when passing state to the TPM inside the callback
     that is invoked to get the TPM's state blob.  See TPMLIB_RegisterCall-
     backs(3).

ERRORS
     TPM_SUCCESS
	 The function completed successfully.

     TPM_SIZE
	 The size of a requested buffer exceeds the limit or the system is out
	 of memory.

     TPM_FAIL
	 An error occurred while attempting to decode the blob.

     For a complete list of TPM error codes please consult the include file
     libtpms/tpm_error.h
