Gets a value from the specified column.
colnum A 2-byte integer. The first column is column 1.
value declaration The arguments required to specify the value depend on the data type. Character and binary data must be mapped into buffers, with the buffer name and length specified in the call. For other data types, a pointer to a variable of the proper type is needed. For character data, the length parameter specifies the length of the C array including the space used for the terminator.
isNULL If a value in a column is NULL, isNull is set to true. In this case, the value argument is not meaningful.
true (1) if successful.
false (0) if unsuccessful.
