Macro Definition Documentation

xroad_binary

#define xroad_binary	(		bin,
			len
	)

Value:

   ({                                                                 \
      void* _b_11_ = (void*)(bin);                                    \
      (xroad_binary_t){_b_11_ == NULL ? 0 : (uint32_t)(len), _b_11_}; \
   })

create xroad_binary_t from binary and its length

xroad_binary_cmp

#define xroad_binary_cmp	(		a,
			b
	)

Value:

({                                                                      \
   xroad_binary_t tmp_1234599 = (a);                                       \
   xroad_binary_t tmp_5432199 = (b);                                       \
   tmp_1234599.len == tmp_5432199.len ?                                 \
      memcmp(tmp_1234599.data, tmp_5432199.data, tmp_1234599.len) :    \
      (tmp_1234599.len < tmp_5432199.len ? -1 : 1);                     \
})

compare two binaries

Returns

the same as for memcmp

xroad_binary_is_null

#define xroad_binary_is_null

(

bin

)

Value:

({                                  \
   xroad_binary_t a = (bin);        \
   (a.len == 0 && a.data == NULL);  \
})

check if binary is null

xroad_binary_null

#define xroad_binary_null   (xroad_binary_t){0, NULL}

null binary
