form_new(3X)                                                form_new(3X)

NAME

       new_form, free_form - create and destroy forms

SYNOPSIS

       #include <form.h>

       FORM *new_form(FIELD **fields);
       int free_form(FORM *form);

DESCRIPTION

       The function new_form creates a new form connected to a specified
       field pointer array (which must be NULL-terminated).

       The function free_form disconnects form from its field array and
       frees the storage allocated for the form.

RETURN VALUE

       The function new_form returns NULL on error.  It sets errno
       according to the function's success:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_CONNECTED
            The field is already connected to a form.

       E_SYSTEM_ERROR
            System error occurred, e.g., malloc failure.

       The function free_form returns one of the following:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_POSTED
            The form has already been posted.

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.
