Getting the file size...

How do I get a file's size in C? I'm only using the standard C library,
nothing else.

Perhaps you should ask on comp.lang.c then?

The usually answer is to open the file (fopen), seek to the end of the
file (fseek), then get your current position (ftell) then close the file
(fclose).

FILE* fp;
fp=fopen("...", "r+b");
if(fp==NULL)
return false;

fseek(fp, 0L, SEED_END);
long length=ftell(fp);
rewind(fp);

....

fclose(fp);
