## SYNOPSIS

### Functions/Subroutines

subroutine **xerbla** (srname, info)\
 **XERBLA**

## Function/Subroutine Documentation

### subroutine xerbla (character\*(\*) srname, integer info)

**XERBLA**

**Purpose:**

```
!>
!> This is a special version of XERBLA to be used only as part of
!> the test program for testing error exits from the LAPACK routines.
!> Error messages are printed if INFO.NE.INFOT or if SRNAME.NE.SRNAMT,
!> where INFOT and SRNAMT are values stored in COMMON.
!>
```

**Parameters**

*SRNAME*

```
!>          SRNAME is CHARACTER*(*)
!>          The name of the subroutine calling XERBLA.  This name should
!>          match the COMMON variable SRNAMT.
!>
```

*INFO*

```
!>          INFO is INTEGER
!>          The error return code from the calling subroutine.  INFO
!>          should equal the COMMON variable INFOT.

```
!>
!>  The following variables are passed via the common blocks INFOC and
!>  SRNAMC:
!>
!>  INFOT   INTEGER      Expected integer return code
!>  NOUT    INTEGER      Unit number for printing error messages
!>  OK      LOGICAL      Set to .TRUE. if INFO = INFOT and
!>                       SRNAME = SRNAMT, otherwise set to .FALSE.
!>  LERR    LOGICAL      Set to .TRUE., indicating that XERBLA was called
