MirBSD manpage: form_userptr(3), set_form_userptr(3)

form_userptr(3)     UNIX Programmer's Manual      form_userptr(3)


     form_userptr - associate application data with a form item


     #include <form.h>
     int set_form_userptr(FORM *form, void *userptr);
     void* form_userptr(const FORM *form);


     Every form and every form item 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 the form
     user pointer field.


     The function form_userptr returns NULL on error. The func-
     tion set_form_userptr returns one of the following:

     E_OK The routine succeeded.

          System error occurred (see errno).


     curses(3), form(3).


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


     These routines emulate the System V forms library.  They
     were not supported on Version 7 or BSD versions.

     The user pointer should be a void pointer.  We leave it as a
     char pointer for SVr4 compatibility.
