[ssudha17]

I am new to Borland...Have worked on Unix only...Please let me know how to pass command line arguments in Borland C++. Urgent.

It should be the same way as in Unix . . . for example:

int main(int argc, char *argv[])
{
.
.
.
}

Argc is the number of arguments being passed to the program and argv is the pointer to the arguments.

Hi!

you declare your entry point in the usual fashion:

int main (int argc, char **argv) for console apps;
int OwlMain (int argc, char **argv) if you use the OWL framework;
etc...

You can transmit the argument from the DOS command line, the same way you do from UNIX terminal;

Or you can also (and that's maybe the point of your question?) transmit the arguments from Borland C++ EDI.

To do so, you have to look in either Options->Project or Options->Environment (sorry, I cannot remember right now since I don't have BCW available). There is one edit box somewhere there that allows you to explicitly write down you arguments. It saves you the trouble of opening a DOS shell.

Don't forget to erase the arguments from the edit box after use, because as far as I remember BCW will not erase it automatically, and all subsequent program launches will be done with the same arguments.



Hope it helps!

Here a short example:

//---------------------------------------------------------------------------
int main(int argc, char **argv)
{
int n;

int done;

struct tm *tms,tm1,tm2;
time_t timer,timer1;
struct ffblk ffblk;
int cday,cmon,cyy,diff,td,tmo,tyy,diffm,diffy;
int day,mon,yy;
char text[256];
char path[256],drive[4],dir[256],name[256],ext[4];
n=argc; //Number of Arguments
if(n!=3)
{
printf("Falsche Anzahl von Argumenten : %d\n",n);
scanf("%c",&text[0]);
exit(2);
}
*argv++; // the first Argument is not needed (Loadfile)
strcpy(text,*argv++); // argument is String
diff=atoi(*argv); // Argument is Integer
