Package: libc6
Version: 2.5-9
dlvsym can fail but does not seem to set dlerror(), contrary to the
manpage, which explains that error conditions should check dlvsym=NULL
and dlerror!=NULL, because 0 is a valid address.
The same can be said about dlsym also.
The following code outputs:
(nil)
which is not expected.
/*BINFMTC: -ldl
dlvsym test code
*/
#define _GNU_SOURCE
#include <dlfcn.h>
#include <stdio.h>
int main()
{
dlerror();
if (!dlvsym(RTLD_NEXT, "chown", "NONEXIST"))
{
printf("%p\n", dlerror());
}
return 0;
}
