使用管道读取和执行操作

Question

I am supposed to read a matrix file, perform operations to the matricies read and output the results of those operations to a different file.

I am fairly new to pipes and I am able to do these oeprations with one process but we are required to run multiple processes. I understand I need to read the file in the parent and pass the necessary numbers to the children who perform the operations, but what's the general way to go about this?

Answer 1

I think what you're looking for is fork() ( http://linux.die.net/man/2/fork )

The use of fork() allows you to duplicate a process.

Try to explain better why you need to do it with multiple processes for more details.
