form_userptr(3X) Library calls form_userptr(3X) NAME set_form_userptr, form_userptr - associate application data with a form item SYNOPSIS #include <form.h> int set_form_userptr(FORM *form, void *userptr); void* form_userptr(const FORM *form); DESCRIPTION Every form and every form item has a field that can be used to hold appli- cation-specific data (that is, the form-driver code leaves it alone). These functions get and set the form user pointer field. RETURN VALUE The function form_userptr returns a pointer (which may be NULL). It does not set errno. The function set_form_userptr returns E_OK (success). 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. AUTHORS Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S. Raymond.
