Hi
I have a error when compile my kernel.
I don't understand the message "implicit declaration of function
`socket' ".
The directive #include <sys/socket.h> has declaration of function
socket.
I don't know if I can do this because the kernel and userland address
spaces are sort seperate, and I must use copyin/copyout.
The function _sys_create_socket is called for a
system call "CreateConection()" that I'm makeing, so
CreateConection() and socket() are system calls,
żIs this a problem?
Thanks for your help.
