# xerbla\_array.f(3)

## NAME

SRC/xerbla\_array.f

## SYNOPSIS

### Functions/Subroutines

subroutine **xerbla\_array** (srname\_array, srname\_len, info)\
 **XERBLA\_ARRAY**

## Function/Subroutine Documentation

### subroutine xerbla\_array (character(1), dimension(srname\_len) srname\_array, integer srname\_len, integer info)

**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.
!>
