    SYNOPSIS

       #include <sys/types.h>
       #include <sys/systm.h>
    int copyin (const void *uaddr void *kaddr size_t len);
    int copyout (const void *kaddr void *uaddr size_t len);
    int copystr (const void *kfaddr void *kdaddr size_t len size_t *done);
    int copyinstr (const void *uaddr void *kaddr size_t len size_t *done);
     

    DESCRIPTION

    The functions are designed to copy contiguous data from one address to another. All but copystr ();
    copy data from user-space to kernel-space or vice-versa.

    The routines provide the following functionality:

    Fn copyin
    Copies Fa len bytes of data from the user-space address Fa uaddr to the kernel-space address Fa kaddr .
    Fn copyout
    Copies Fa len bytes of data from the kernel-space address Fa kaddr to the user-space address Fa uaddr .
    Fn copystr
    Copies a NUL-terminated string, at most Fa len bytes long, from kernel-space address Fa kfaddr to kernel-space address Fa kdaddr . The number of bytes actually copied, including the terminating NUL, is returned in Fa *done (if Fa done is non- NULL
    Fn copyinstr
    Copies a NUL-terminated string, at most Fa len bytes long, from user-space address Fa uaddr to kernel-space address Fa kaddr . The number of bytes actually copied, including the terminating NUL, is returned in Fa *done (if Fa done is non- NULL

     

    RETURN VALUES

    The functions return 0 on success or Er EFAULT if a bad address is encountered. In addition, the copystr (,);
    and copyinstr ();
    functions return Er ENAMETOOLONG if the string is longer than Fa len bytes.
