       to a user address space

SYNOPSIS    [Toc]    [Back]

       int copyout(
               caddr_t kernel_src,
               caddr_t user_dest,
               u_int bcount );

ARGUMENTS    [Toc]    [Back]

       Specifies the address in kernel space of the  data  to  be

       The copyout routine copies a specified amount of data from
