command line string parsing / pointer confusion

[rhboarder]

i have a small app to be compiled into a .lib file. it accepts a char * array
and the array count, outputs a '-' and then reads in a line and (supposed) to
parse it into the recieved char * arrays. i know im doing something wrong
with writing to the memory locations but i cant figure it out. heres the code:

const int MAX_CHARS = 255;

extern "C"
MYAPI void getArgs(int argC, char * argV[])
{
	char holder[MAX_CHARS];

	cout << "-";
	cin.getline(holder, MAX_CHARS-1);
	strcat(holder, "\0");
	int index=0; //array index
                nBytes=1; //#of bytes to copy
                pos=0; //placeholder in holder string
	int chr;
	for (int i = 0; i < (int)strlen(holder)+1; i++)
	{
		chr = (int)*(char*)&holder[i];
		if (chr == 32 || chr == 0) //space or end string
		{
			if (index < argC)
			{
                                //copy nBytes-1, (nbytes is the string + the 
                                //space char or end string
				memcpy(&argV[index], &holder[pos], nBytes-1);
				pos = i+1;	//skip whitespace in $ holder
				index++;
			} else break;
			nBytes = 1;
		} else nBytes++;
	}
}

//in the host application that calls that
const int MAX_ARGS = 4;
char * args[MAX_ARGS];
getArgs(2, args); //is it ok to use a number smaller than the
                 //actual # char* arrays?
