Wondering if anyone can point out my mistake: The code core dumps during the second iteration of the infinite loop. Here's the sample code:

struct input {
char *message;
};

...
for (;;) {
struct input *in = (struct input *) malloc
(sizeof(struct input)) ;
char *buffer = (char *)malloc(140 * sizeof
(char)) ;
ReadFromMsgQueue(to buffer) ;

in->message = (char *)malloc(140 * sizeof(
char);

free(buffer) ;
free(in->message) ;
free(in);
}

Works during the first iteration. However, during the second one, the code core dumps at in->message = (char *)...

Any tip is highly appreciated.

I copied and pasted this code and it works. I eliminated ReadFromMsgQueue(to buffer) ;
and added )to the end of
in->message = (char *)malloc(140 * sizeof(char));
and its working maybe the problem was the missing ).

Thanks for the reply.

After few hours of troubleshooting, I figured out that the problem was with synchronization of the structure variable from the main part of the program and within the thread.

The first mistake was passing the address of the structure and deleting it within the thread.
