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 following 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>.
