Имя (Name)

set_field_userptr, field_userptr - associate application data
       with a form field

---

Синопсис (Synopsis)

#include <form.h>

       int set_field_userptr(FIELD *field, void *userptr);
       void *field_userptr(const FIELD *field);

Описание (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.

---

Возвращаемое значение (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).

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.
