exception Gsl_exn of (errno * string)
val init : unit -> unit
Gsl_error.init () setups the GSL error handler so that the OCaml function Gsl_error.handler gets called in case of an error.
val uninit : unit -> unit
Gsl_error.uninit () reverts the GSL error handler to its previous definition. The default GSL error simply aborts the program.
val handler : (errno * string -> unit) Pervasives.ref
The OCaml handler for GSL errors. Initially set to Gsl_error.default_handler. If the function returns, the error is ignored and execution of the GSL function continues.

Redefine it so as to ignore some particular errors (EOVRFLW or EUNDRFLW for instance).

val default_handler : errno * string -> 'a
The default OCaml handler for GSL errors. It simply raises the Gsl_error.Gsl_exn exception.
