|
* 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.
|
|
*
|
|
* Arguments
|
|
* =========
|
|
*
|
|
* SRNAME_ARRAY (input) CHARACTER(1) array, dimension (SRNAME_LEN)
|
|
* The name of the routine which called XERBLA_ARRAY.
|
|
*
|
|
* SRNAME_LEN (input) INTEGER
|
|
* The length of the name in SRNAME_ARRAY.
|
|
*
|
|
* INFO (input) INTEGER
|
|
* The position of the invalid parameter in the parameter list
|
|
* of the calling routine.
