need programs that illustrate use of settimer and alarm functions in GNU C
问题 Can anyone illustrate the use of settimer or alarm function in gnu C , with some program examples ,please ? I have a program that continuously processes some data , and i need to set a timer / alarm that goes off every t seconds , in response to which , i need to store the processed data into a file. This file writing has to be asynchronous < i.e. the data processing and file writing must not wait for each other > . I went through the GNU C Library pages , but i couldn't understand much..
