 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\&.
