subroutine xerbla_array (SRNAME_ARRAY, SRNAME_LEN, INFO)
XERBLA_ARRAY
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 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.
