This reuse the "json_callback_*" implemented for the yajl parser as they don't really need to be changed. It's just awkward to have to cast between `unsigned char` and `char.` Replace few strncpy() by memcpy() to let the compiler know we want to copy the string without the terminating nul, as we are adding it just after. Also, it should be possible to keep using YAJL parser when json-c library isn't available. Signed-off-by: Anthony PERARD <anthony.perard@vates.tech> Reviewed-by: Jason Andryuk <jason.andryuk@amd.com>
