<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
Every form and every form item has a field that can be
|
|
|
|
|
used to hold application-specific data (that is, the form-
|
|
|
|
|
driver code leaves it alone). These functions get and set
|
|
|
|
|
the form user pointer field.

<H2>PORTABILITY</H2><PRE>
|
|
|
|
|
These routines emulate the System V forms library. They
|
|
|
|
|
were not supported on Version 7 or BSD versions.
|
|
|
|
|
|
|
|
|
|
The user pointer should be a void pointer. We leave it as
|
|
|
|
|
a char pointer for SVr4 compatibility.
