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 standard input; that is, the window you are in when you type the jwin command. 

SEE ALSO

layers(1). 

EXAMPLE

bytes:  86 25
