     SUBYTE(K)                 UNIX System V                 SUBYTE(K)



     Name
          subyte - stores a character in user data space

     Syntax
          int
          subyte(addr, val)
          unsigned char *addr, val;

     Description
          The subyte routine stores one character in the user's data
          space.  If you are storing data in u.u_base, consider using
          passc(K) in that u.u_count, u.u_offset, and u.u_base are
          updated for you, and error handling is provided via
          u.u_error.  If any chance exists that a -1 may be contained
          in the data that you are storing in user space, use
          copyout(K) instead of subyte (or passc).  A -1 in the data
          is usually associated as an error condition.

          This routine must not be called from an interrupt or xxinit
          routine.

     Parameters
          The argument addr is a pointer to the byte to be stored in
          the user's data space.

          The argument val is the value to be stored.
