What is the best way to copy data from one FILE stream to another...

This is in C

I'm talking like a 300GB zip file, I was just using

Code:FILE *fp1, *fp2;
char c;

fp1 = fopen("/opt/test.zip", "rb");
fp2 = fopen("/home/user/dest.zip", "w+b");

c = fgetc(fp1);
while (c != EOF)
{
fputc(c, fp2);
c = fgetc(fp1);
}

fclose(fp1);
fclose(fp2);
