pipe function

pipe creates two file descriptors which can be used by parent and child processes to communicate data. A child process can be created with the fork function.

	Library: unistd.h
	Prototype: int pipe(int fd[2]);
	Syntax: int fd[2];
		 pipe(fd);

Once the pipe has been executed, the data can be transfered using read and write.

Examples:
