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
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
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
.
