Experiment to see what works best for your data on your hardware. Now, write 2is a system call which traps into the kernel. Details fwrite began as a community contribution with pull request by Otto Seiskari.
We may be able to support one or two more specific options if required. Modern machines almost surely have more than one CPU so fwrite uses them; on all operating systems including Linux, Mac and Windows. Along with the structure definition, a variable emp of type struct employee is also declared.
