Detailed Description

• mruby exception throwing handler

See Copyright Notice in mruby.h

WARNING: This header is for mruby core internal use only. Do not include this header in user code or mrbgems.

When MRB_USE_CXX_EXCEPTION is defined, this header requires C++ compilation. C source files that include this header will fail to compile when linked into C++ projects using MRB_USE_CXX_EXCEPTION.

For exception-safe code in mrbgems and user code, use the mrb_protect_error() API from <mruby/error.h> instead:

#include <mruby/error.h>

mrb_value my_func_body(mrb_state *mrb, void *data) { // code that may raise exceptions return result; }

void my_func(mrb_state *mrb) { mrb_bool error; mrb_value result = mrb_protect_error(mrb, my_func_body, data, &error); // cleanup code runs here regardless of exception if (error) mrb_exc_raise(mrb, result); }
