NAME

6       MAPGTR - Gets the current value of a specified EZMAP parameter of type
7       REAL.
8
9       MPGETR is an alternate name for the routine MAPGTR.
10

SYNOPSIS

12       CALL MAPGTR (PNAM,RVAL)
13

C-BINDING SYNOPSIS

15       #include <ncarg/ncargC.h>
16
17       void c_mapgtr (char *pnam, float *rval)
18

DESCRIPTION

20       PNAM        (an input expression of type CHARACTER) specifies the name
21                   of the parameter to get. Only the first two characters of
22                   the string are examined.
23
24       RVAL        (an output variable of type REAL) receives the value of the
25                   parameter specified by PNAM.
26

C-BINDING DESCRIPTION

28       The C-binding argument descriptions are the same as the FORTRAN
29       argument descriptions.
30

USAGE

32       This routine allows you to retrieve the current value of EZMAP
33       parameters.  For a complete list of parameters available in this
34       utility, see the ezmap_params man page.
35

EXAMPLES

37       Use the ncargex command to see the following relevant example: mpex07.
38

ACCESS

40       To use MAPGTR, MAPGETR, or c_mapgtr load the NCAR Graphics libraries
41       ncarg, ncarg_gks, and ncarg_c, preferably in that order.
42

MESSAGES

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