# DESCRIPTION

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.

# RETURN VALUES

E_OK
  The function was successful.
E_BAD_ARGUMENT
  A bad argument was passed to the function.
