Subject: cpp-common/bt2c: make CStringView convertible from std::string
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=a0ae532f4ebf0a5d31f8378fd0584d420e9eca7e

cpp-common/bt2c: make CStringView convertible from std::string

This will make it possible to have functions that accept CStringViews:

    void foo(CStringView);

and pass in std::strings seamlessly:

    foo(myStdStr);
