form_userptr - associate application data with a form item SYNOPSIS
#include <form.h> int set_form_userptr(FORM *form, void *userptr); void* form_userptr(const 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 NULL on error. The function set_form_userptr returns one of the following: E_OK The routine succeeded. E_SYSTEM_ERROR System error occurred (see errno). SEE ALSO
curses(3X), form(3X). 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. AUTHORS
