Function Documentation

mrb_load_irep()

mrb_value mrb_load_irep ( mrb_state * mrb, const uint8_t * bin )

extern

load mruby bytecode functions

Please note! Currently due to interactions with the GC calling these functions will leak one RProc object per function call. To prevent this save the current memory arena before calling and restore the arena right after, like so

 int ai = mrb_gc_arena_save(mrb);
 mrb_value status = mrb_load_irep(mrb, buffer);
 mrb_gc_arena_restore(mrb, ai);

Also, when called from a C function defined as a method, the current stack is destroyed. If processing continues after this function, the objects obtained from the arguments must be protected as needed before this function.
