field_userptr(3FORM)													      field_userptr(3FORM)

NAME

       form_field_userptr - associate application data with a form field

SYNOPSIS

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

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.

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).

SEE ALSO

       ncurses(3NCURSES), form(3FORM).

NOTES

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

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.
