GCLSG (Close segment) – closes a GKS segment. SynopsisCALL GCLSG C-Binding Synopsis#include <ncarg/gks.h> void gclose_seg( void ); UsageA call to GCLSG closes the currently open segment (graphics output primitives will no longer be stored in that segment). GCLSG can be called only if a segment is open. AccessTo use GKS routines, load the NCAR GKS-0A…
