SYNOPSIS

  Functions/Subroutines

subroutine xerbla_array (SRNAME_ARRAY, SRNAME_LEN, INFO)
XERBLA_ARRAY

Function/Subroutine Documentation

  subroutine xerbla_array (character(1), dimension(srname_len)SRNAME_ARRAY, integerSRNAME_LEN, integerINFO)

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:
    SRNAME_ARRAY

              SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN)
              The name of the routine which called XERBLA_ARRAY.

    SRNAME_LEN

              SRNAME_LEN is INTEGER
              The length of the name in SRNAME_ARRAY.

    INFO

              INFO is INTEGER
              The position of the invalid parameter in the parameter list
              of the calling routine.
