xerbla_array

Assists other languages in calling the
xerbla
function.

Syntax

call xerbla_array
(
srname_array
,
srname_len
,
info
)

Description
The routine assists other languages in calling the error handling
xerbla
function. Rather than taking a Fortran string argument as the function name,
xerbla_array
takes an array of single characters along with the array length. The routine 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
, the routine will call
xerbla
with a string of all blank characters.
If some macro or other device makes
xerbla_array
available to
C99
by a name
lapack_xerbla
and with a common Fortran calling convention, 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
.
Output Parameters
srname_array
CHARACTER(1)
.
Array, dimension (
srname_len
). The name of the routine that called
xerbla_array
.
srname_len
INTEGER
.
The length of the name in
srname_array
.
info
INTEGER
.
Position of the invalid parameter in the parameter list of the calling routine.
