form_field_userptr 3X 2024-03-16 "ncurses @NCURSES_MAJOR@.@NCURSES_MINOR@" "Library calls"
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 application-specific data
(that is, the form-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.
