Include System Call in POK

[AtirChaudary]

i have been trying to understand syscall.c and .h file and how you have implemented your system calls my question is if i want to add (( #include<sys/sockets.h )) which is a system call , how will i do it as pok will have its own system calls.
i want to use linux systems calls in pok kindly guide me on this ?
