Greetings and Salutations to all! I became interested in writing code that takes advantage of pthreads and of course decided to write a little "it really works" program. I went ahead and wrote a little program that builds a small queue with two threads, one which writes the queue and one that reads the queue.
The program works rather well and I was proud of myself... at least until
I changed:
struct que {
struct item *head;
struct item *tail;
};
into:
struct que {
struct item *head;
struct item *tail;
int counter;
};
When I make this one tiny change, the program stops working by
supposedly segfaulting on the pthread_create call. However I was able to
realize by copious debugging printfs that the thread I am creating is
indeed running.
What have I done wrong? I can't find anything wrong, nor can about half a
dozen of my friends that have worked with pthreads before.
As a side note, I'm compiling with :
gcc -g -Wall threadexamp.c -o threadexamp -lpthread
