### NAME

post_form, unpost_form - form library

### LIBRARY

Curses Form Library (libform, -lform)

### SYNOPSIS

```int` post_form(```FORM *form`)
```int` unpost_form(```FORM *form`)

### DESCRIPTION

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.

### RETURN VALUES

The functions will return one of the following error values:

```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 function.
