I have a C# Class. I need to execute its instance at regular intervals say 5 minutes. I need to execute this code every 5 minutes without blocking the main thread. Also I would like to have a mechanism where I can stop this process.

Sometimes it's convenient to have I/O that doesn't block i.e we don't want a read call to block on one in case of input from the other. Solution for this is the given function: To specify non-blocking option: #include<fcntl. h> int fd; fcntl(fd, F_SETFL, O_NONBLOCK);
By default, read() waits until at least one byte is available to return to the application; this default is called “blocking” mode.
Yes, absolutely. If the write buffer is full, the write can block.
Blocking a signal means telling the operating system to hold it and deliver it later. Generally, a program does not block signals indefinitely—it might as well ignore them by setting their actions to SIG_IGN . But it is useful to block signals briefly, to prevent them from interrupting sensitive operations.
