*> \par Purpose:
|
|
* =============
|
|
*>
|
|
*> \verbatim
|
|
*>
|
|
*> 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.
|
|
*> \endverbatim
|
|
*
|
|
* Arguments:
|
|
* ==========
|
|
*
|
|
*> \param[in] SRNAME_ARRAY
|
|
*> \verbatim
|
|
*> SRNAME_ARRAY is CHARACTER(1) array, dimension (SRNAME_LEN)
|
|
*> The name of the routine which called XERBLA_ARRAY.
|
|
*> \endverbatim
|
|
*>
|
|
*> \param[in] SRNAME_LEN
|
|
*> \verbatim
|
|
*> SRNAME_LEN is INTEGER
|
|
*> The length of the name in SRNAME_ARRAY.
|
|
*> \endverbatim
|
|
*>
|
|
*> \param[in] INFO
|
|
*> \verbatim
|
|
*> INFO is INTEGER
|
|
*> The position of the invalid parameter in the parameter list
|
|
*> of the calling routine.
