Access Violation Error with cstring

[Lang]

My declaration:

	char * tempToken;
	tempToken = "";

What's giving the error:

strcpy_s(tempToken, tempInt, tempString);

Both tempInt and tempString have valid values. I have a struct called Node that has a token and a link to another Node (for a linked list). I've tried

strcpy_s(v->token, tempInt, tempString);

And the error THAT gave me something along the lines of DST != NULL && sizeInByte > 0

I've tried char tempToken[100]; as a declaration and char *tempToken = ""; and char * tempToken = malloc(sizeof(char)*100);

I'm banging my head against the wall here. Anyone tell me what I'm doing wrong?

Thanks in advance,
Lang
