lsetxattr()/lgetxsttr() functions are not working on a ext4 symlink.
But works fine on a regular file.
I tried the following program.. Not sure if I am missing something.
Any help will be appreciated.
--------- simple program -------------
[jvrao]# cat sxl.c
#include <stdio.h>
#include <sys/types.h>
#include <attr/xattr.h>
main()
{
int ha=5;
int ha_out=-1;
int err;
err = lsetxattr("./foo", "user.junk", &ha, sizeof(int),0);
if (err == -1)
perror("lsetxattr failed");
lgetxattr("./foo", "user.junk", &ha_out, sizeof(int));
if (err == -1)
perror("lsetxattr failed");
printf("file:./foo ha:%d ha_out:%d\n", ha, ha_out);
ha_out = -1;
err = lsetxattr("./foo.sl", "user.junk", &ha, sizeof(int),0);
if (err == -1)
perror("lsetxattr failed");
lgetxattr("./foo.sl", "user.junk", &ha_out, sizeof(int));
if (err == -1)
perror("lsetxattr failed");
printf("file:./foo.sl ha:%d ha_out:%d\n", ha, ha_out);
}
------------------------
[jvrao]# ls -l foo*
-rw-r--r--. 1 root root 0 2010-03-31 16:49 foo
lrwxrwxrwx. 1 root root 3 2010-03-31 16:49 foo.sl -> foo
[jvrao]# ./sxl
