Thread: Passing arguments to function...

i'm using the arguments to main and then passing them to another function to open a file with the argument as the file name...this is the code:

Code:

int main(int argc, char* argv[])
{
     char *fname;
     fname = argv[1];
     readFile(fname);
}

this is the readFile function:

Code:

void readFile(char *file)
{
     ifstream fin (file);

}

it doesn't work...what am i doing wrong? i've only given the pertinent code...

Regards,
