Read 5 bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as a 40‐bit, signed.
Synopsis

int
get40BitIntegerValue(
bsls::Types::Int64* value,
std::streambuf* streamBuf);Description
2's‐complement, big‐endian integer. Return 0 if successful, and a non‐zero value otherwise. The operation succeeds if all 5 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 a 40‐bit, signed, 2's‐complement, big‐endian integer.
Return Value
0 on success, and a non‐zero value otherwise
