Thread: Struct/parse returning wrong information

So I have the following parsing code that sends of a string in msgbuf comprised of binary information:

Code:

parse_binaryxyz(msgbuf,&xyz);
                new_nav_posecef = TRUE;
               (#1) printf("%x %x %x %x %x %d %d %d %d %x %d %d\n",xyz.header[0],xyz.header[1],xyz.msg_class,xyz.msg_id, xyz.len, xyz.ITOW, xyz.ECEF_X, xyz.ECEF_Y, xyz.ECEF_Z, xyz.Pacc, xyz.cs[0], xyz.cs[1]);
				//Reset variables
				gettingbinarymsg = FALSE;
				msgbufindex = 0;

The msgbuf is sent here where the information is split up into its meanings by a predifined struct that is listed below the following code:

Code:

int parse_binaryxyz(unsigned char *msg, struct nav_posecef *xyz)

{

	if ((msg[2] == 0x01) && (msg[3] == 0x01))

	{//Parse the NAV_POSECEF message

		//Cast the message into the nav_posecef structure

		xyz = (struct nav_posecef*) msg;
        (#2)printf("%x %x %x %x %x %d %d %d %d %x %d %d\n",xyz->header[0],xyz->header[1],xyz->msg_class,xyz->msg_id, xyz->len, xyz->ITOW, xyz->ECEF_X, xyz->ECEF_Y, xyz->ECEF_Z, xyz->Pacc, xyz->cs[0], xyz->cs[1]);

		return 0;

	}

}

So I have a struct that is of the form:

Code:

struct nav_posecef{
	unsigned char header[2];
	unsigned char msg_class;
	unsigned char msg_id;
	unsigned short len;
	unsigned long ITOW;
	long ECEF_X ;
        long ECEF_Y ;
        long ECEF_Z ;
	unsigned long Pacc;
	unsigned char cs[2];
}__attribute__((packed));

Alright here is my problem: You can see the two printf commands: The one labeled (#2) ,inside the actual parsing code, prints out the correct information. However, (#1) , where the information is returned does not. Why is it not passing the information back to the main program correctly.

The following is a what I see printing to the screen: (Note the first line is from the parser and correct and second is what is returned)

0 0 0 0 0 -1312895732 234 0 1122304 2 4 0

Would that still give me the format of the struct I created so that I could print out the information separately inside my main program once returned? Where would it be placed? After

Code:

xyz = (struct nav_posecef*) msg;

or in replace of it?

THank you so much. I think that last suggestion fixed my problem. That is a huge weight off my shoulders. Thanks again.
