[PATCH 07/12] util/util.c: avoid clang error on vsnprintf

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



clang by default doesn't seem to like printf calls with non-literal
format strings.
Add the proper pragma to disable this warning in the report function
to make kvmtool compile with clang. Despite its GCC name, clang also
accepts this.
