XERBLA(l)							   BLAS routine 							 XERBLA(l)

NAME

       XERBLA - i an error handler for the LAPACK routines

SYNOPSIS

       SUBROUTINE XERBLA( SRNAME, INFO )

	   CHARACTER*6	  SRNAME

	   INTEGER	  INFO

PURPOSE

       XERBLA  is an error handler for the LAPACK routines.  It is called by an LAPACK routine if an input parameter has an invalid value.  A mes-
       sage is printed and execution stops.

       Installers may consider modifying the STOP statement in order to call system-specific exception-handling facilities.

ARGUMENTS

       SRNAME  (input) CHARACTER*6
	       The name of the routine which called XERBLA.

       INFO    (input) INTEGER
	       The position of the invalid parameter in the parameter list of the calling routine.

	       End of XERBLA

NAME

       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, 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.
