form_userptr(3)						       form_userptr(3)

NAME
       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 a pointer (which may be NULL).	 It
       does not set errno.

       The function set_form_userptr returns E_OK (success).

SEE ALSO
       curses(3), form(3).

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 is a void pointer.  We chose not to leave it as a char
       pointer for SVr4 compatibility.
