[fpc-pascal] Redirecting input to a child process

[Ludo Brands]

Pipe handles can be used directly with readfile:
Var BytesRead:Longword;
 
windows.Readfile(mProcess.Output.Handle,str1[1],BytesAvailable,BytesRead,nil
);
can replace 
        mProcess.OutPut.Read(str1[1], BytesAvailable);

I meant the program's own handles. Like instead of doing:

    Read(input, c);

read directly from a handle:

    Windows.ReadFile(inputHandle, ...);
