This routine returns a string which can be used as an HDS component name. The string describes the current PGPLOT graphics device. It is intended for use in identifying resources related to the graphics device (such as palette and colour table), stored within HDS files.

For most devices, the returned name is simply the PGPLOT device type. For GWM windows, the returned string includes the name of the gwm window (so that each window can have separate resources).

CALL KPG1_PGHNM( NAME, STATUS )

NAME = CHARACTER $\ast$ ( DAT__SZNAM ) (Returned)

STATUS = INTEGER (Given and Returned)

• A graphics device must previously have been opened using PGPLOT.
