The difference between operating systems

Windows has a series of different system calls that cover all the kernel operations. Many of these correspond exactly with the Unix equivalent. Here's a list of some of the overlapping system calls:

	Windows	Unix
Process control	`CreateProcess()` `ExitProcess()` `WaitForSingleObject()`	`fork()` `exit()` `wait()`
File manipulation	`CreateFile()` `ReadFile()` `WriteFile()` `CloseHandle()`	`open()` `read()` `write()` `close()`
File protection	`SetFileSecurity()` `InitializeSecurityDescriptor()` `SetSecurityDescriptorGroup()`	`chmod()` `umask()` `chown()`
Device management	`SetConsoleMode()` `ReadConsole()` `WriteConsole()`	`ioctl()` `read()` `write()`
Information maintenance	`GetCurrentProcessID()` `SetTimer()` `Sleep()`	`getpid()` `alarm()` `sleep()`
Communication	`CreatePipe()` `CreateFileMapping()` `MapViewOfFile()`	`pipe()` `shmget()` `mmap()`
