.SH DESCRIPTION
|
|
|
|
|
Every form field 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
|
|
|
|
|
that field.
|
|
|
|
|
.SH RETURN VALUE
|
1999-10-24 12:32:42 +08:00

|
|
The function \fBfield_userptr\fR returns \fBNULL\fR on error. The function
|
1997-05-15 12:00:00 +08:00
|
|
|
\fBset_field_userptr\fR returns one of the following:
|

|
|
|
|
|
\fBE_SYSTEM_ERROR\fR

|
|
|
|
|
.SH SEE ALSO
|
|

\fBcurses\fR(3X), \fBform\fR(3X).
|
|

|
|
.SH NOTES
|
|
|
|
|
The header file \fB<form.h>\fR automatically includes the header file
|
|
|
|
|
\fB<curses.h>\fR.
|
|
|
|
|
.SH PORTABILITY
|
|
|
|
|
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.
