NAME

6       set_field_userptr,  field_userptr  -  associate application data with a
7       form field
8

SYNOPSIS

10       #include <form.h>
11
12       int set_field_userptr(FIELD *field, void *userptr);
13       void *field_userptr(const FIELD *field);
14

DESCRIPTION

16       Every form field has a field that can be used to hold  application-spe‐
17       cific  data  (that  is,  the  form-driver code leaves it alone).  These
18       functions get and set that field.
19

RETURN VALUE

21       The function field_userptr returns a pointer (which may be  NULL).   It
22       does not set errno.
23
24       The function set_field_userptr returns E_OK (success).
25

SEE ALSO

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

NOTES

30       The  header  file  <form.h>  automatically  includes  the  header  file
31       <curses.h>.
32

PORTABILITY

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