= PDAF_interfaces_module =

|| **Note:** `PDAF_interfaces_module` was replaced by the **[wiki:Module_PDAF module PDAF]** in PDAF V3.0. It is only availble in PDAF versions ||

The module `PDAF_interfaces_module` provides interface definitions for the routines of PDAF. If you like to use explicit Fortran interfaces, or if you have to use them in case of the smoother, you have to include the following line in the header you the calling routine:

{{{
  use PDAF_interfaces_module
}}}

Using `PDAF_interface_module` is recommended, but not required.
