<H2>DESCRIPTION</H2><PRE>
|
2010-08-01 08:45:28 +08:00
|
|
|
Every form and every form item has a field that can be
|
1997-05-15 12:00:00 +08:00
|
|
|
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.

These routines emulate the System V forms library. They
|
1997-05-15 12:00:00 +08:00
|
|
|
were not supported on Version 7 or BSD versions.

The user pointer is a void pointer. We chose not to leave
|
|
|
|
|
it as a char pointer for SVr4 compatibility.
