It is usually a system call , implemented in the kernel . Fork is the primary (and historically, only) method of process creation on Unix-like operating systems. 3.pipe pipe() creates a pipe, a unidirectional data channel that can be used for interprocess ommunication. The array pipefd is used to return two file descriptors referring to the ends of the pipe. pipefd[0] refers to the read end of the pipe. pipefd[1] refers to the write end of the pipe. Data written to the write end
