dup_field(FIELD *field, int frow, int fcol);
link_field(FIELD *field, int frow, int fcol);
new_field(int rows, int cols, int frow, int fcol, int nrows, int nbuf);
The dup_field() function duplicates the given field, including any buffers associated with
the field and returns the pointer to the newly created field. free_field() destroys the
field and frees any allocated resources associated with the field. The function
link_field() copies the given field to a new field at the location frow and fcol but shares
the buffers with the original field. new_field() creates a new field of size rows by cols
at location frow, fcol on the page, the argument nrows specified the number of off screen
rows the field has and the nbuf parameter specifies the number of extra buffers attached to
the field. There will always be one buffer associated with a field.
On error dup_field() and new_field() will return NULL. The functions will one of the fol-
lowing error values:
E_OK The function was successful.
E_BAD_ARGUMENT A bad argument was passed to the function.
E_CONNECTED The field is connected to a form.
The header <form.h> automatically includes both <curses.h> and <eti.h>.
