2019-04-26libcamera: utils: call secure_getenv() if it exists or workaround with ↵Giulio Benetti
issetugid() When secure_getenv() is not available, need to have a workaround. Check if secure_getenv() is present, otherwise call issetugid() on its place.

2019-04-19libcamera: Include header related to source file firstLaurent Pinchart
Include the header file corresponding to the source file in the very first position. This complies with the Google C++ coding style guideliens, and helps ensuring that the headers are self-contained. Three bugs are already caught by this change (missing includes or forward declarations) in device_enumerator.h, event_dispatcher_poll.h and pipeline_handler.h. Fix them.

The secure_getenv() call is not provided by all C libraries. Support this feature by implementing our own version. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2019-04-03libcamera: utils: Use internal basename implementation.Kieran Bingham
Differing implementations of basename() exist, some of which may modify the content of the string passed as an argument. The implementation of basename() is trivial, thus to support different C librariese, provide our own version which accepts and returns a const char *. Update the call sites to use the new implementation. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
