SYNOPSIS
#include <form.h>
int set_form_userptr(FORM *form, char *userptr);
char form_userptr(FORM *form);
DESCRIPTION
Every form and every form item has a field that can be used to hold application-specific data (that is, the formdriver code leaves it alone). These functions get and set the form user pointer field.
RETURN VALUE
The function form_userptr returns NULL on error. The function each function _form_userptrfR returns one of the following:
E_OK The routine succeeded.
NOTES
The header file <form.h> automatically includes the header file <curses.h>.
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.
