Dfuse_hl and Interception library

Colin Ngam
 

Greetings,

 

Just a couple quick questions:

  1. What is the difference between “aliased intercept” and “single intercept”?
  2. What’s the purpose of __wrap_XXX definition?

Example:
__attribute__((visibility("default"))) int __wrap_fclose (FILE *) __attribute__((weak, alias("dfuse_" "fclose")));

 

Thanks.

Hi,

 

How do I turn on IOIL_PRELOAD for the build?

 

Thanks.
