Passing a struct about my_basic

[paladin-t]

There is a byte array field in the mb_value_t struct, which you can store some bytes in. For example passing a struct (sizeof(64) bytes) through MY-BASIC:

typedef struct Tag {
	char c0[64];
} Tag;

mb_static_assert(sizeof(mb_val_bytes_t) >= sizeof(Tag));

static int test0(struct mb_interpreter_t* s, void** l) {
	int result = MB_FUNC_OK;
	mb_value_t val;

	mb_assert(s && l);

	mb_check(mb_attempt_open_bracket(s, l));

	mb_check(mb_attempt_close_bracket(s, l));

	Tag tag;
	for (int i = 0; i < sizeof(tag.c0) - 1; ++i)
		tag.c0[i] = '*';
	tag.c0[sizeof(tag.c0) - 1] = '\0';
	val.type = MB_DT_USERTYPE;
	memset(&val.value.bytes, 0, sizeof(mb_val_bytes_t));
	memcpy(&val.value.bytes, &tag, sizeof(Tag));

	mb_check(mb_push_value(s, l, val));

	return result;
}

static int test1(struct mb_interpreter_t* s, void** l) {
	int result = MB_FUNC_OK;
	mb_value_t val;

	mb_assert(s && l);

	mb_check(mb_attempt_open_bracket(s, l));

	mb_make_nil(val);
	mb_check(mb_pop_value(s, l, &val));

	mb_check(mb_attempt_close_bracket(s, l));

	Tag tag;
	memcpy(&tag, &val.value.bytes, sizeof(Tag));

	printf(tag.c0);

	return result;
}

Test it with:

test1(test0())

By default, the byte array typed mb_val_bytes_t is defined as large as maximum of sizes of void*, unsigned long, int_t, real_t, in my_basic.h. Make sure you've redefined it large enough to store your struct:

typedef unsigned char mb_val_bytes_t[64];

I've documented this feature in the wiki.

I will try this! Thanks a lot 😃

I have to say, that the MY-BASIC documentation is almost too good! 🥇

I just finished binding my SpriteSheets to MY-BASIC - it works wonderfully.
For me, this issue has been resolved.
Thanks a lot! :)
