jwin(C)                         19 June 1992                         jwin(C)


 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.
