ncl_mapgtl - Man Page

MAPGTL — Gets the current value of a specified EZMAP parameter of type LOGICAL.

MPGETL is an alternate name for the routine MAPGTL.

CALL MAPGTL (PNAM,LVAL)

#include <ncarg/ncargC.h>

void c_mapgtl (char *pnam, int *lval)

PNAM

(an input expression of type CHARACTER) specifies the name of the parameter to get. Only the first two characters of the string are examined.

LVAL

(an output variable of type LOGICAL)  receives the value of the parameter specified by PNAM.

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

This routine allows you to retrieve the current value of EZMAP parameters.  For a complete list of parameters available in this utility, see the ezmap_params man page.

The capabilities offered by the MAPGTL or MPGETL routines are also offered by the MAPGTI or MPGETI routines. See the examples listed on the MAPGTI or MPGETI man page.

To use MAPGTL, MPGETL, or c_mapgtl load the NCAR Graphics libraries ncarg,  ncarg_gks, and ncarg_c, preferably in that order.

See the ezmap man page for a description of all EZMAP error messages and/or informational messages.
