NAME

       MAPGTR - Gets the current value of a specified EZMAP parameter of type REAL.

       MPGETR is an alternate name for the routine MAPGTR.

SYNOPSIS

       CALL MAPGTR (PNAM,RVAL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_mapgtr (char *pnam, float *rval)

DESCRIPTION

       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.

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

C-BINDING DESCRIPTION

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

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.

EXAMPLES

       Use the ncargex command to see the following relevant example: mpex07.

ACCESS

       To use MAPGTR, MAPGETR, or c_mapgtr load the NCAR Graphics libraries ncarg, ncarg_gks, and
       ncarg_c, preferably in that order.

MESSAGES

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