module Printexc =
struct ... end
exn -> string
Printexc.to_string e returns a string representation of
('a -> 'b) -> 'a -> 'b
Printexc.print fn x applies
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.
('c -> 'd) -> 'c -> 'd
Printexc.catch fn x is similar to
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
Printexc.catch does. Moreover, calling
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.
