.SH NAME
MAPGTR - 
Gets the current value of a specified EZMAP parameter
of type REAL. 
.sp
MPGETR is an alternate name for the routine MAPGTR.
.SH SYNOPSIS
CALL MAPGTR (PNAM,RVAL)
.SH C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>
.sp
void c_mapgtr (char *pnam, float *rval)
.SH DESCRIPTION 
.IP PNAM 12
(an input expression of type CHARACTER) specifies the name of the
parameter to get. Only the first two characters of the string are
examined. 
.IP RVAL 12
(an output variable of type REAL)
receives the value of the parameter
specified by PNAM.
.SH C-BINDING DESCRIPTION
The C-binding argument descriptions are the same as the FORTRAN 
argument descriptions.
.SH USAGE
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.
.SH EXAMPLES
Use the ncargex command to see the following relevant
example: mpex07.
.SH ACCESS
To use MAPGTR, MAPGETR, or c_mapgtr load the NCAR Graphics libraries ncarg, 
ncarg_gks, and ncarg_c, preferably in that order.
.SH MESSAGES
See the ezmap man page for a description of all EZMAP error
messages and/or informational messages.
