XERBLA_ARRAY

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.
