:mrdocs:

Read the specified `bufferLength` number of bytes from the input sequence of the specified `streamBuf`, as if by a call to `streamBuf‐>sgetn(buffer, bufferLength)`, and load the bytes into successive elements of the specified `buffer`, starting at the first element. Return 0 on success, 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. If less than `bufferLength` bytes are read, the number of bytes loaded into `buffer` is not specified. The behavior is undefined unless `0 <= bufferLength` and `buffer` is the address of a sequence of at least `bufferLength` bytes.
