In which include file EPERM (returned by pthread_mutex_unlock) error code is declared?

Can anyone give me the right direction for this, as I am not able to find the declaration of EPERM in either pthread.h or errno.h (on openSUSE Linux). I found this in asm-generic/errno-base.h but is this the right one? Why its not in errno.h? Thanks
