Thread: va_arg for creating a stack

Dear experts ,

i want to create a stack of arguments with va_arg, which is getting i think but when i try to read them back, means traverses the stack it gives me null please tell me proper way of cerating and traversing i am trying like this.

Code:

char ss[1000];
char ........_ptr = (char *)((((int)ss)+(7)) & ~7);
char *........_pp = (char **)((((int)ss)+(7)) & ~7);
char *va_curptr = 0;
int ss_cnt=0;



char *sendList(int numArgs,...)
{
	
	int type;
	
	va_list vlist;
	
	va_start(vlist,numArgs);
	va_curptr = vlist;           
      /* assume
0 -> int
* 1 -> float
* 2 -> string
*/
                                  switch(type)
		{
		case 0:	
		         ss_ptr = (va_arg(vlist,int));
		         ss_ptr += (vlist - va_curptr);
		         va_curptr = vlist;
		         ss_cnt += sizeof(int);
			break;
			
		case 1:
		          ss_fp = (double *)ss_ptr;
		          ss_fp = ((double *)(&va_arg(vlist,double)));
		         ss_ptr += (vlist - va_curptr);
		         va_curptr = vlist;
		         ss_cnt += sizeof(double);
                                           break;
                            case 2:   
		        ss_pp = (char **)ss_ptr;
		        ss_ptr =(char *)(&va_arg(vlist,char *));
		        ss_ptr += (vlist - va_curptr);
		        va_curptr = vlist;
		        ss_cnt += sizeof(char *);
}
return ss;
}


int main()
{
	char * temp_ptr = sendList(6,2,"hello",1,12.25,0,34);

//here i want to write a code to get the values of stack how to do.
return 0;

}

so syntactically it is correct please tell proper way of passing any integer , float and string value inot the stack and also how to extract from stack please tell me
