    NAME

    form_new - 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>.
