pos_form_cursor — position a form window cursor
int pos_form_cursor(FORM *form);
The function pos_form_cursor restores the cursor to the position required for the forms driver to continue processing requests. This is useful after curses routines have been called to do screen-painting in response to a form operation.
This routine returns one of the following:
The routine succeeded.
Routine detected an incorrect or out-of-range argument.
The form has not been posted.
System error occurred (see errno).
The header file <form.h> automatically includes the header file <curses.h>.
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
