NAME

6       form_field_userptr - associate application data with a form field
7

SYNOPSIS

9       #include <form.h>
10       int set_field_userptr(FIELD *field, void*userptr);
11       void *field_userptr(const FIELD *field);
12

DESCRIPTION

14       Every  form field has a field that can be used to hold application-spe‐
15       cific data (that is, the form-driver  code  leaves  it  alone).   These
16       functions get and set that field.
17

RETURN VALUE

19       The  function  field_userptr returns a pointer (which may be NULL).  It
20       does not set errno.
21
22       The function set_field_userptr returns E_OK (success).
23

SEE ALSO

25       curses(3X), form(3X).

NOTES

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

PORTABILITY

32       These  routines emulate the System V forms library.  They were not sup‐
33       ported on Version 7 or BSD versions.
34
35       The user pointer is a void pointer.  We chose not to leave it as a char
36       pointer for SVr4 compatibility.
