exception Gsl_exn of errno * string
Error.Gsl_exn is raised by GSL to indicate an error. The second argument gives the reason for the error.
val init : unit -> unit
Error.init () setups the GSL error handler so that the OCaml function Error.handler gets called in case of an error. This behavior is the default now.
val uninit : unit -> unit
Error.uninit () reverts the GSL error handler to the default of the GSL C-library. The default GSL error simply aborts the program.
val handler : (errno -> string -> unit) Pervasives.ref
The OCaml handler for GSL errors. Initially set to 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 Error.Gsl_exn exception.
val strerror : errno -> string
strerror e returns a description of the error e.
val string_of_errno : errno -> string
string_of_errno e returns the name of e.
val printer : exn -> string option
printer is an exceoption printer for Exn. It is registered by default with Printexc.
