Read the specified bufferLength number of bytes from the input sequence of the specified streamBuf, as if by a call to `streamBuf->sgetn(buffer.
Declared in <balber_berutil.h>
static
int
getChars(
char* buffer,
std::streambuf* streamBuf,
int bufferLength);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.
0 on success, and a non-zero value otherwise
