     field_count, form_fields, move_field, set_form_fields -- form library

     Curses Form Library (libform, -lform)

     #include <form.h>

     field_count(FORM *form);

     FIELD **
     form_fields(FORM *form);

     move_field(FIELD *field, int frow, int fcol);

     set_form_fields(FORM *form, FIELD **fields);

     The field_count() function returns the number of fields that are attached to the given form,
     if the form argument passed is NULL then field_count() will return -1.  The function
     form_fields() will return a pointer to array of attach fields for the given form, this array
     is not NULL terminated, fields may be attached to the given form by calling
     set_form_fields().  The fields argument in this function is a pointer to a NULL terminated
     array of fields that will be attached to the form.  If there are already fields attached to
     the form then they will be detached before the new fields are attached.  The new fields
     given must not be attached to any other form.  The move_field() function will move the given
     field to the location specified by frow and fcol.

     Functions returning pointers will return NULL if an error is detected.  The functions that
     return an int will return one of the following error values:

     E_OK		The function was successful.
     E_CONNECTED	The field is connected to a form.
     E_POSTED		The form is currently posted to the screen.
     E_BAD_ARGUMENT	The function was passed a bad argument.

     curses(3), forms(3)

     The header <form.h> automatically includes both <curses.h> and <eti.h>.
