JWIN(C)                              UNIX System V



     Name
          jwin - print size of layer


     Syntax
          jwin


     Description
          The jwin command runs only under layers(C) 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.


     Diagnostics
          Returns 0 on successful completion, 1 otherwise.

          If layers(C) has not  been  invoked,  an  error  message  is
          printed:
          jwin: not mpx


     Note
          The layer whose size is  printed  is  the  one  attached  to
          standard input; that is, the window you are in when you type
          the jwin command.
