(** [Printexc.print fn x] applies [fn] to [x] and returns the result.

If the evaluation of [fn x] raises any exception, the

name of the exception is printed on standard error output,
|
|
and the exception is raised again.
|

The typical use is to catch and report exceptions that

escape a function application. *)

val catch : ('a -> 'b) -> 'a -> 'b
|
|
(** [Printexc.catch fn x] is similar to {!Printexc.print}, but
|
|
aborts the program with exit code 2 after printing the
|
|
uncaught exception. This function is deprecated: the runtime
|
|
system is now able to print uncaught exceptions as precisely
|
|
as [Printexc.catch] does. Moreover, calling [Printexc.catch]
|
|
makes it harder to track the location of the exception
|
|
using the debugger or the stack backtrace facility.
|
|
So, do not use [Printexc.catch] in new code. *)
