NAME
       copyoutstr  -  General:	Copies	a null-terminated string from a kernel
       address space to a user address space

SYNOPSIS
       int copyoutstr(
	       char *kernel_src,
	       char *user_dest,
	       int maxlength,
	       int *lencopied );

ARGUMENTS
       Specifies the address in kernel space of the null-terminated string  to
       be copied.  Specifies the address in user space to copy the null-termi‐
       nated string to.	 Specifies the maximum number of bytes to copy.	 Spec‐
       ifies the actual length of the string copied.

DESCRIPTION
       The  copyoutstr	routine copies a specified null-terminated string from
       the protected kernel address space  to  the  unprotected	 user  address
       space.

CAUTIONS
       If  the	string	being copied is not null-terminated, copyoutstr copies
       maxlength bytes into the user address space.

RETURN VALUES
       Upon successful completion, copyoutstr returns the value 0  (zero)  and
       the  actual length of the string copied in lencopied. Otherwise, it can
       return the following errors: The address in kernel space that you spec‐
       ified in the kernel_src argument cannot be accessed.  The length of the
       string exceeds the maxlength value.
