Subject: Add extern "C" guard to public header
X-Git-Tag: 0.12.2~21
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=29505ecf25b33364ee7472ac58018b8b9195d49d;p=libass

Add extern "C" guard to public header

Our public headers can be #included from C++. Hence, ass.h needs
an extern "C" guard to declare the correct linkage for functions.
ass_types.h only defines types, so it does not need a guard.
