RE: Rioplay and xPL

[Tony T]

Hi all,

Have got Rioplay compiling and listening to xPL messages :-)
(Currently does play/stop/light on/light off)

However, I was holding the array of message elements in a global, but as
the
routine is threaded when it is processing a valid command, the global
structure is getting overwritten by other incoming messages.

Can any C programmers please advise on the following, please?

I thought the best way was to define the array within the thread and then
pass a pointer to the array to the sub functions that do the processing.
But
I get an error during comilation:

Base operand of '->' has non-pointer type 'xpl_msg_struc'

These are some relevant code snippets:

typedef struct xpl_msg_struc {
char section[35];
char name[17];
char value[129];
};

int xPLParser(const char* xplmsg, struct xpl_msg_struc *, unsigned int
xpl_msg_index);

Then in the thread:

struct xpl_msg_struc xpl_msg[20], *pxpl_msg;
unsigned int xpl_msg_index = 0;
pxpl_msg=&xpl_msg[0]; (tried without the [0])

Calling the function:
xPLParser(mesg, pxpl_msg, xpl_msg_index)

The function is:
int xPLParser(const char* xplmsg, struct xpl_msg_struc * pxpl_msg, unsigned
int xpl_msg_index) {

A typical line causing the error is:
strcpy(pxpl_msg[xpl_msg_index]->section, xpl_section);

I'm sure I must be doing something stupid, but I havent used C for many
years.

Any ideas?

Many thanks
Tony
