Getting the command tail

How do i get the command tail and parse it into an array, kinda like C++?

How about a proc to return the command tail?

what's the command tail?

C:\FOO\MAN\CHOO\MYPROG test.txt

ahh, you get a pointer to that in WinMain, say you use a standard C style procedure for WinMain (or whatever the starting procedure is) something like this


proc WinMain

push ebp
mov ebp, esp ;store the stack pointer in ebp
;so we can get at the parameters


;any code you need for your program


mov esp, ebp
pop ebp
ret 10;

endp WinMain


ebp is then a pointer to the bottom of the stack just after you pushed ebp

so ebp points to what is essentially a structure

struct
{
unsigned long Old_EBP;
void* Return_Address;
HINSTANCE hInstance;
HINSTANCE hPrevInstance;
LPSTR lpCmdLine;
int nCmdShow;
} Wot_EBP_Points_To;


so [ebp + 10h] is a pointer to a null terminated char array which contains the command tail, the string will stay in memory until the end of the winmain procedure, which should be the end of your program.

hope it helps

Im doing it in dos, if i was using windows i would call "GetCommandLine".
