Hello,

I'm trying to use the pthread_self function that supposed to be existed at cthreads unit.
However the compiler tell me that it does not know "pthread_self".

I'm using Linux 64 bit (so I can't use libc), using fpc 2.2.0 . Looking at the source of cthreads.pp, it does have an include for pthread.inc file, that does contain dynamic/static linking of the function, so what am I missing ?

It's only imported into that unit (in the implementation), it's not exported. The cthreads unit only installs a thread manager, it does not expose any implementation details (that's the whole point of that unit).

If you want to use the RTL support for threading, use the generic RTL routines and not OS-specific ones. There is e.g. a GetCurrentThreadId function (but don't count on it returning the same value as pthread_self).

If you want to program with pthreads directly, use the pthreads unit instead.

Thanks, that works.
