form_userptr(3) Library calls form_userptr(3)
NAME
set_form_userptr, form_userptr - associate application data with a form
item
SYNOPSIS
#include <form.h>
form_userptr(3) *form, void *userptr);
form_userptr(3) FORM *form);
DESCRIPTION
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.
RETURN VALUE
The function form_userptr returns a pointer (which may be NULL). It
does not set errno.
The function set_form_userptr returns E_OK (success).
PORTABILITY
These routines emulate the System V forms library. They 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.
