hi, i am reading the code about system call. after the sys_ipc_wrapper (in file kern/syscalls.cpp) is called.it get the thread's pointer by current_thread and then get the Syscall_frame. the code is like this: ... Thread *curr=current_thread(); Syscall_frame *f = curr->regs(); ... i can not understand the relationship between curr->regs() and the system call's stack frame. _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
