API and data structure syntax

SQL_STRUCTURE sqlchar
{
        short length;
        _SQLOLDCHAR data[1];
};

This is not defined in any header file. The following is an example that shows how to define the structure in COBOL:

* Replace maxlen with the appropriate value:
01 SQLCHAR.
49 SQLCHAR-LEN  PIC S9(4) COMP-5.
49 SQLCHAR-DATA PIC X(maxlen).
