[lttng-dev] [PATCH] Use uint32_t for lttng_viewer_stream.metadata_flag

[Marc-André Laperle]

I'm not sure that's possible. Whether I change them to uint8_t or int8_t, I get warnings because they get used with strncpy which wants char. Any idea how to solve this?

While you are at it, you could change the char fields as well, since char is not exact-width either.
