NAME
set_field_userptr,
field_userptr -
associate application data with a form field
SYNOPSIS
#include <form.h>
int set_field_userptr(FIELD *field, void *userptr);
void *field_userptr(const FIELD *field);
DESCRIPTION
Every form field has a field that can be used to hold applicatio-specific data
(that is, the for-driver code leaves it alone).
These functions get and set
that field.
RETURN VALUE
The function field_userptr returns a pointer (which may be
NULL).
It does not set errno.
The function set_field_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.
