C编程指针如何把数字的地址传递给函数？

嗨，我有一个简单的指针相关问题。我想把指针传递给函数函数（VAT**PTR，size）；我可以把字符串传递给这个函数，就像函数（“Microchip”，9）；如果我想通过一个变量，我可以像这个CHAR＝0x90那样做；函数（ANP；A 1）；我想通过十六进制数为EX0x90；FU。这是错误的。如何把这个数字的地址传递给函数？问候，Akshay

    Hi,

    I have simple pointer related question.
I want to pass pointer to function
Function(void *ptr,size);

I can pass string to this function like
Function("Microchip",9);

If I want to pass single variable I can do it like this
char a=0x90;
Function(&a,1);
What is I want to pass hex number for ex 0x90;
Function(0x90,1);----This is wrong.
How to pass address of this number to the function?

Regards,
Akshay
