Hi,
You can pass a structure by reference by passing the address of the structure and in the called function accept the address of the structure in a variable which is of type pointer to the structure.



e.g.struct p

{

	int i;	char c;

};

void func(struct p*);

void main()

{

	struct p myp;

	myp.i=10;	myp.c='a';

	func(&myp);

}

void func(struct p *mp)

{

	printf("%d %c",mp->i,mp->c);

}
HTH,
