I discovered what should I do: You cannot change the address of an IPv6 nameserver dynamically in your program though.

High level mock functions only work on x86 because they go under C and inject machine code. Back to the main topic, we interposition our replacement i.

Or just fake it You may be able to avoid any of this by clever use of header files, i. Types of interpositions Back to the main topic, we interposition our replacement i. The resolver state is the same resolver state that is used for the cove "main" thread.
High level mock functions only work on x86 because they go under C and inject machine code.
Libresolv Source Code -
Email Required, but never shown. A lot of the examples call the compiler directly, so you end up doing cargo cult programming, trawling open codd project code for the correct recipe to stick in your own Makefile.
Unicorn Meta Zoo 9: We recommend to use the new thread-safe interfaces in new code, since the traditional interfaces have been deprecated by the BIND folks. Looking forward, I found out that the resolver functions are within the glibc6 library.

What am I doing wrong? For compatibility with other older systems you might want to continue to use those interfaces llbresolv. Your mock functions are given precedence pre-loaded so when the application code tries to define that function, it is already there. How do we handle problem users? Asked 5 years, 3 months ago.

The traditional resolver interfaces soudce, continue to use a single resolver state and are therefore still thread-unsafe. So googling for the more general term interpositioning rather than mocking tends to result in more useful search results, and a common example given is how to replace malloc with your own interpretation or wrapper of malloc. C has no such high level mocking support. So this is the function!

This is probably all you need to know and you can take it from here. You may be able to avoid any of this by clever use of header files, i. Stack Overflow works best libfesolv JavaScript enabled. Post as a guest Name. The C standard is revised only once per decade, and any changes tend to reflect existing features the compilers already support.
One approach seems to be more popular than the other two. Back to the main topic, we interposition our replacement i. But, using gethostbyname directly from the code, using wget or browsing the web I can't get it right.
Giving the linker the argument —wrap and the name of the symbol s you want to wrap, changes how those symbols are resolved.
I added some file writting commands there and it worked like a charm. When an executable object file is loaded into memory, dynamically linked, and then executed. When the source code is compiled Link time:
