In the Octave interpreter we set this to a function that throws an exception and transfers control to the enclosing try/catch block. That is typically at the top-level REPL.

To build shared libraries of those packages on Windows requires that all symbols be known when the shared library is constructed. If we call error directly, that would mean that the BLAS and LAPACK libraries would have to depend on Octave... */ static xerbla_handler_fptr xerbla_handler = nullptr; extern "C" void octave_set_xerbla_handler (xerbla_handler_fptr fcn) { xerbla_handler = fcn; } /* Replacement for BLAS and LAPACK XERBLA subroutine that calls an optionally installed handler function. */ F77_RET_T F77_FUNC (xerbla, XERBLA) (F77_CONST_CHAR_ARG_DEF (s_arg, len), const F77_INT& info F77_CHAR_ARG_LEN_DEF (len)) { const char *s = F77_CHAR_ARG_USE (s_arg); int slen = F77_CHAR_ARG_LEN_USE (s_arg, len); std::cerr << std::string (s, slen) << ": parameter number " << info << " is invalid" << std::endl; if (xerbla_handler) (*xerbla_handler) (); F77_RETURN (0) }
