implementation of dummies methods

Hi all,

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,
