in libc/src/lib/libc there is Dummies.cc file which contains many methods.
Actually i am trying to port ISAKMP which use most of them ( such as fork, getuid ,
socketpair, sendmsg and etc) .  i was able to compile it but i face many no implementation for " method" message , so I think i need to implement all these methods, am i right ?!

from where i should start, should i use new libc  plugin or i should implement them in specific places. 

 
thank you in advance .

best,
