JWIN(1)              INTERACTIVE UNIX System              JWIN(1)



          NAME
               jwin - print size of layer

          SYNOPSIS
               jwin

          DESCRIPTION
               The jwin command runs only under layers(1) and is used to
               determine the size of the layer associated with the current
               process.  It prints the width and the height of the layer in
               bytes (number of characters across and number of lines,
               respectively).  For bit-mapped terminals only, it also
               prints the width and height of the layer in bits.

          EXIT STATUS
               Returns 0 on successful completion, 1 otherwise.

          DIAGNOSTICS
               If layers(1) has not been invoked, an error message is
               printed:

                    jwin: not mpx


          NOTE
               The layer whose size is printed is the one attached to stan-
               dard input; that is, the window you are in when you type the
               jwin command.

          SEE ALSO
               layers(1).
