Gets the current value of a specified ezmap parameter of type real. mpgetr is an alternate name for the routine mapgtr.
CALL MAPGTR (PNAM,RVAL)
#include <ncarg/ncargC.h>
void c_mapgtr (char *pnam, float *rval)
(an input expression of type CHARACTER) specifies the name of the parameter to get. Only the first two characters of the string are examined.
(an output variable of type REAL) 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.
Use the ncargex command to see the following relevant example: mpex07.
To use MAPGTR, MAPGETR, or c_mapgtr 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.
