form_userptr(3) UNIX Programmer's Manual form_userptr(3)
form_userptr - associate application data with a form item
#include <form.h>
int set_form_userptr(FORM *form, void *userptr);
void* form_userptr(const FORM *form);
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.
The function form_userptr returns NULL on error. The func-
tion set_form_userptr returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
curses(3), form(3).
The header file <form.h> automatically includes the header
file <curses.h>.
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.
