Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the contents octets of BER-encoded integer value according to the specification. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of an integer value according to the specification. The program is ill-formed unless the specified INTEGRAL_TYPE is a fundamental integral type.
