NAME

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

SYNOPSIS

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

DESCRIPTION

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

RETURN VALUE

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

SEE ALSO

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

NOTES

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

PORTABILITY

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