11f3d5a431
This patch is the first in a series that aims at cleaning up the public C library headers (which end up being distributed with the NDK). <resolv.h> and <time.h> contain declarations that should not be public. They are used by other parts of the platform, but NDK applications should not use or rely on them. So copy them to private <bionic_time.h> and <resolv_iface.h> headers and use a guard macro to avoid conflicts when both headers are included at the same time. The idea is that we're going to fix the other platform modules to include these private headers. After this is done, we will remove the duplicate definitions from <resolv.h> and <time.h> Change-Id: I121c11936951c98ca7165e811126ed8a4a3a394d
