Selecting a driver
In a UNIX environment, you can use pipe-device arrays to connect custom programs to the input or output of the onpload utility. Although pipe-device arrays provide the simplest way to customize the input or output of onpload, connecting the standard I/O of programs is less efficient than directly incorporating the functionality into onpload.
The ipload utility identifies custom software by the driver name that you assign to the record-format definitions.
To incorporate custom file-handling software directly into the onpload program:
- Use the API described in Available API support functions to write the driver.
- Add the driver name to the onpload database. For details, see Adding a custom-driver name.
- Select the driver from the Driver selection list in the Format Options window. For details, see Format options.
