2.9 Using an FML Typed Buffer

To use FML typed buffers, you must perform the following steps:

• Set the appropriate environment variables.
• Describe the potential fields in an FML field table.
• Create an FML header file and specify the header file in a #include statement in the application.

FML functions are used to manipulate typed buffers, including those that convert fielded buffers to C structures and vice versa. By using these functions, you can access and update data values without having to know how data is structured and stored. For more information on FML functions, see Oracle Tuxedo ATMI FML Function Reference.
