The struct is initialized with he expression { 0 }, which generates a compile warning:

/tmp/android-sdk-hproxy/android-sdk/src/hicn/ctrl/libhicnctrl/src/api.c:568:36: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]

Because all the embers of the struct must be intialized to {0} separately.

Warning can be fixed using a memset()
