* 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.
