call psb_get_boundary(bndel, desc, info)
- On Entry
- the communication descriptor.
Specified as: a structured data of type descdatapsb_desc_type.
- On Return
- The list of boundary elements on the calling process, in
Specified as: a rank one array with the ALLOCATABLE
attribute, of type integer.
- Error code.
An integer value; 0 means no error has been detected.
- If there are no boundary elements (i.e., if the local part of
the connectivity graph is self-contained) the output vector is set
to the ``not allocated'' state.
- Otherwise the size of
bndel will be exactly equal to the
number of boundary elements.
