Fork()

[dmxd99]

Fork() may be used to create a child process in unix but I am compiling my c codes in visual studio 6.0 and the equivalent API is createProcess() However I have to stick with ANSI C therefore I can't use createProcess() so is there another API that create a child process that can run in Visual studio without using data type such as HANDLE, DWORD, LPVOID etc...
Thanks

ANSI Standards don't fork. fork is a POSIX standard and will be found on all *nix boxes (Linux,Unix,BSD,etc.)... createProcess is the closest thing you can get to fork, because that's how they handle the system call.

You could use conditional marcos/preprocessor directives to define how your doing things so that it can be compiled under both.

Can you give me a sample code or further explain how conditional macros/preprocessor directives can be used...

The only ANSI way to create a new process is with the [tt]system[/tt] function. It usually passes its argument to the OS's main "shell" as a command to parse (maybe?) and execute.

The commands you must pass to it, however, won't work reliably on all OSs (e.g. Unix [tt]ls[/tt] vs. DOS [tt]dir[/tt]), so it's not portable at all. It can also be very insecure.
