Subject: gethostbyname and resolv.conf
FYI: Looks like the musl gethostbyname() doesn't use the "search" command
in the resolv.conf file.
$ cat test_gethostbyname.c
#include <stdio.h>
#include <netdb.h>
int main(int argc, char *argv[])
{
struct hostent *lh = gethostbyname(argv[1]);
if (lh)
puts(lh->h_name);
else
herror("gethostbyname");
return 0;
}

$ make test_gethostbyname
gcc test_gethostbyname.c -o test_gethostbyname
