selinux context_new return value question

selinux context_new return value question

[Gaurav Kumar]

According to http://linux.die.net/man/3/context_new, "On success, zero
is returned" but none of the functions mentioned return 0. They are
all returning const char * or void. Can someone please clarify in
which case 0 will be returned? In other words, how can I find out if
call to context_new succeeded?

Thanks,
Gaurav

It is a bug.  NULL (0) actually would be the error code.  Since context_new is
basically doing a malloc of a new structure.

I will fix the code in Fedora and work to get it upstream.
