SUBROUTINE ZERRHE( PATH, NUNIT )
*
* -- LAPACK test routine (version 3.2) --
* Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..
* November 2006
*
* .. Scalar Arguments ..
CHARACTER*3 PATH
INTEGER NUNIT
* ..
*
* Purpose
* =======
*
* ZERRHE tests the error exits for the COMPLEX*16 routines
* for Hermitian indefinite matrices.
*
* Note that this file is used only when the XBLAS are available,
* otherwise zerrhe.f defines this subroutine.
*
* Arguments
* =========
*
* PATH (input) CHARACTER*3
* The LAPACK path name for the routines to be tested.
*
* NUNIT (input) INTEGER
* The unit number for output.
