Hi Vijay,
By looking with google and experimenting, I found out that your posix
version will work if you cast the parameter in the structure properly:
printf("Size of %s, uid %d, is %d\n", argv[1], sb.st_uid, (long)sb.st_size);
The "(long)sb.st_size" being the key thing.
As discussed here: http://curl.haxx.se/mail/lib-2003-12/0232.html

So the type of st_size is off_t

Hi,
I am writing a simple program to print the size of a file on disk. But
surprisingly my program keeps printing 0 on Darwin (but works on a PC
running Linux). Here's two set of programs I wrote, one using stat posix api
and other using Carbon CoreServices. Neither of them works. If someone can
tell me whats wrong or suggest a way of getting file size correctly, please
let me know.
Thanks
Vijay
Posix:
--------
#include <stdio.h>
#include <stdlib.h>
#include <sys/stat.h>
main(int argc, char **argv)
{
struct stat sb;
int retval;
if(argc<2){
fprintf(stderr,"Usage: %s <filename>\n", argv[0]);
exit(1);
}
retval = stat(argv[1], &sb);
if(retval==0) printf("Size of %s, uid %d, is %d\n", argv[1], sb.st_uid,
sb.st_size);
else perror("stat");
}
CoreServices:
-------------------
OSStatus PrintFileSize(char *path)
{
OSStatus err=noErr;
FSRef ref;
FSCatalogInfo cataloginfo;
err = FSPathMakeRef("/Users/vijayv/dd.txt", &ref, NULL);
require_noerr(err, CantMakeRef);
err = FSGetCatalogInfo (&ref, kFSCatInfoDataSizes, &cataloginfo, NULL,
NULL, NULL);
require_noerr (err, CantGetCatalogInfo);
printf("File size is %d\n", cataloginfo.dataLogicalSize);
return err;
CantMakeRef:
printf("Cant make ref\n");
CantGetCatalogInfo:
printf("Cant get catalog info\n");
return err;
}
