The lrd_col_data function sets a pointer to the data of a specific column. This function accesses data without performing a bind operation. Note that to reference data (through pointers) you must cast it to its appropriate type. lrd_col_data only appears in the print.inl file located in the script directory.

When you retrieve data using lrd_col_data, you must convert the character strings into printable data using lrd_to_printable.

For more details refer to the Function Header File lrd.h in the include directory.
