This function wraps rcutils_get_executable_name and takes care of the allocator and throws an exception when an error occurs. The rcutils_get_executable_name implementation doesn't set any error information when it fails, and from reading through the implementation and the documentation for the system functions it calls, an error should be extremely unlikely. A generic failure message is the best I can do. Signed-off-by: Scott K Logan <logans@cottsay.net>
