   form_userptr.3x    ( 3 )

связать данные приложения с элементом формы (associate application data with a form item)

Имя (Name)

set_form_userptr, form_userptr - associate application data with
       a form item

Синопсис (Synopsis)

#include <form.h>

int set_form_userptr(FORM *form, void *userptr); void* form_userptr(const FORM *form);


Описание (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.

Возвращаемое значение (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).

Примечание (Note)

The header file <form.h> automatically includes the header file
       <curses.h>.

Портативность (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.
