xerbla_array

Syntax

Include Files

The FORTRAN 77 interfaces are specified in the mkl_lapack.fi include file (to be used in Fortran programs) and in the mkl_lapack.h include file (to be used in C programs).

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_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.
