I am confused about the pthread_t type in FreeBSD 5.3, can you help.. Based on /usr/include/pthread.h, typedef struct pthread *pthread_t; and when I look for the declaration of "struct pthread" , all I find is a forward declaration with a comment that says, /* * Forward structure definitions. * * These are mostly opaque to the user. */ struct pthread; That is 'struct pthread' is an opaque type.... Then in my application, when I try to find my thread_id, I say cout << "my tid is " << pthread_self() << endl; and I get a hex value. Which is syntactically correct, but semantically in-correct. I'm not interested in the pointer, I'm interested in the numerical thread ID... Now at this point, you'll think all you have to do is to de-reference the pointer. But since 'struct pthrad' is opaque, gdb and myself are clueless to proceed from here. Can someone shed some light on this please... Thankshome | help
