post_form, unpost_form - form library
The post_form() function performs the actions necessary to present the
form on the curses screen. If there are any init functions that need to
be called then they will be called prior to the form being posted and the
cursor will be positioned on the first active field that can be visited.
Conversely, the function unpost_form() removes the form from the screen
and calls any termination functions that were specified.
Functions returning pointers will return NULL if an error is detected.
The functions that return an int will return one of the following error
E_OK The function was successful.
E_BAD_ARGUMENT A bad argument was passed to the function.
E_POSTED The form is already posted to the screen.
E_NOT_POSTED The form was not posted to the screen.
E_NOT_CONNECTED There are no fields associated with the form.
E_BAD_STATE The function was called from within a init or term
The header <form.h> automatically includes both <curses.h> and <eti.h>.
