SUBROUTINE XERBLA_ARRAY(SRNAME_ARRAY, SRNAME_LEN, INFO)
*
* -- LAPACK auxiliary routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* September 19, 2006
*
IMPLICIT NONE
* .. Scalar Arguments ..
INTEGER SRNAME_LEN, INFO
* ..
* .. Array Arguments ..
CHARACTER(1) SRNAME_ARRAY(SRNAME_LEN)
* ..
*
* Purpose
* =======
*
* 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.
*
* Arguments
* =========
*
* SRNAME_ARRAY (input) CHARACTER(1) array, dimension (SRNAME_LEN)
* The name of the routine which called XERBLA_ARRAY.
*
* SRNAME_LEN (input) INTEGER
* The length of the name in SRNAME_ARRAY.
*
* INFO (input) INTEGER
* The position of the invalid parameter in the parameter list
* of the calling routine.
