Manual Pages  — form_field_userptr

NAME

set_field_userptr, field_userptr - associate application data with a form field

CONTENTS

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.

Like a classics radio station whose play list spans decades, Unix simultaneously exhibits its mixed and dated heritage. There's Clash-era graphics interfaces; Beatles-era two-letter command names; and systems programs (for example, ps) whose terse and obscure output was designed for slow teletypes; Bing Crosby-era command editing (# and @ are still the default line editing commands), and Scott Joplin-era core dumps.
