module Printexc: sig end
Facilities for printing exceptions.
val to_string : exn -> string
Printexc.to_string e returns a string representation of
the exception e.
val print : ('a -> 'b) -> 'a -> 'b
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.
