:mrdocs:

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.
