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.
