ncl_ngckop(3) - Linux man page

Name

NGCKOP - a function to check if a specified GKS workstation is open.

INTEGER FUNCTION NGCKOP(WKID)

#include <ncarg/ncargC.h>

int c_ngckop(int wkid)

WKID (an input variable of type INTEGER) specifying a GKS workstation identifier.

The C binding argument descriptions are the same as the FORTRAN argument descriptions.

The function returns a "1" if the workstation identified by WKID is open, otherwise it returns a "0".

IOPEN = NGCKOP(WKID)

sets IOPEN to "1" if WKID is open and sets IOPEN to "0" otherwise.

To use NGCKOP or c_ngckop, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
