subroutine XERBLA_ARRAY	(	CHARACTER(1), dimension(srname_len)	SRNAME_ARRAY,
		INTEGER	SRNAME_LEN,
		INTEGER	INFO
	)

XERBLA_ARRAY

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.
 

Parameters:

[in]	SRNAME_ARRAY	SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN) The name of the routine which called XERBLA_ARRAY.
[in]	SRNAME_LEN	SRNAME_LEN is INTEGER The length of the name in SRNAME_ARRAY.
[in]	INFO	INFO is INTEGER The position of the invalid parameter in the parameter list of the calling routine.
