Inccorect work SQLDescribeCol

We encountered a problem that when calling the SQLDescribeCol moth with an empty buffer (ColumnName) and the value of the variable BufferLength == 0, columnNameLength is not returned for a subsequent correct call with correct memory allocation
Example:
SQLDescribeCol(
handle,
ColumnNumber,
nullptr,
0,
&columnNameLength,
&DataType,
&ColumnSize,
&DecimalDigits,
&Nullable);
