*       SUBROUTINE XERBLA_ARRAY(SRNAME_ARRAY, SRNAME_LEN, INFO)
*
*       .. Scalar Arguments ..
*       INTEGER SRNAME_LEN, INFO
*       ..
*       .. Array Arguments ..
*       CHARACTER(1) SRNAME_ARRAY(SRNAME_LEN)
*       ..
*
*
*> \par Purpose:
*  =============
*>
*> \verbatim
*>
*> XERBLA_ARRAY assists other languages in calling XERBLA, the LAPACK
*> and BLAS error handler.  Rather than taking a Fortran string argument
*> as the function's name, XERBLA_ARRAY takes an array of single
*> characters along with the array's length.  XERBLA_ARRAY then copies
*> up to 32 characters of that array into a Fortran string and passes
*> that to XERBLA.  If called with a non-positive SRNAME_LEN,
*> XERBLA_ARRAY will call XERBLA with a string of all blank characters.
*>
*> Say some macro or other device makes XERBLA_ARRAY available to C99
*> by a name lapack_xerbla and with a common Fortran calling convention.
*> Then a C99 program could invoke XERBLA via:
*>    {
*>      int flen = strlen(__func__);
*>      lapack_xerbla(__func__, &flen, &info);
*>    }
*>
*> Providing XERBLA_ARRAY is not necessary for intercepting LAPACK
*> errors.  XERBLA_ARRAY calls XERBLA.
*> \endverbatim
*
*  Arguments:
*  ==========
*
*> \param[in] SRNAME_ARRAY
*> \verbatim
*>          SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN)
*>          The name of the routine which called XERBLA_ARRAY.
*> \endverbatim
*>
*> \param[in] SRNAME_LEN
*> \verbatim
*>          SRNAME_LEN is INTEGER
*>          The length of the name in SRNAME_ARRAY.
*> \endverbatim
*>
*> \param[in] INFO
*> \verbatim
*>          INFO is INTEGER
*>          The position of the invalid parameter in the parameter list
*>          of the calling routine.
