Hi All,

We have API exit and Security exit programs which need to collect thread id when invoked. The exit code works in Solaris. But the same code is printing negative values in linux - rhel3. We are using

sprintf(thread_id,"SecExit: TID:%i", pthread_self());

Using "%d" or "%l" or "%ld" instead of "%i" didn't help.

Please help.

TIA.

In Solaris, pthread_t is of type unsigned int. In RHEL3, it is of type unsigned long int. We were getting this problem as we were reading thread id as int("%i"). It got solved by reading thread id as unsigned long int("%lu" ). Hence issue is related to OS.....nothing specific to MQ/Exits....... Now we are getting positive values as thread ids. But surprisingly these thread ids are very large values - 10 digit numbers though there will be only 10-15 threads.

Regards,
Kalpana
