form_field_userptr(3X) Library calls form_field_userptr(3X) NAME set_field_userptr, 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-spe- cific 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). PORTABILITY These routines emulate the System V forms library. They were not sup- ported 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.
