NAME

6       DPGETR - Retrieves the real value of an internal parameter of type REAL
7       or INTEGER.
8

SYNOPSIS

10       CALL DPGETR (PNAM,RVAL)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       void c_dpgetr (char *pnam, float *rval)
16

DESCRIPTION

18       PNAM        (an input expression of type CHARACTER) specifies the name
19                   of the parameter to get. The name must appear as the first
20                   three characters of the string.  Other characters may be
21                   used to document the use of the parameter being retrieved;
22                   for example, instead of just ´LS1´, one can use ´LS1 -
23                   LABEL SPACING PARAMETER 1´.
24
25       RVAL        (an output variable of type REAL) is the name of the
26                   variable into which the value of the internal parameter
27                   specified by PNAM is to be retrieved.  If the internal
28                   parameter is a value "r" of type REAL, the value returned
29                   is "r".  If the internal parameter is a value "i" of type
30                   INTEGER, the value returned is "REAL(i)".
31

C-BINDING DESCRIPTION

33       The C-binding argument descriptions are the same as the FORTRAN
34       argument descriptions.
35

USAGE

37       This routine allows you to retrieve the current value of Dashpack
38       parameters.  For a complete list of parameters available in this
39       utility, see the dashpack_params man page.
40

ACCESS

42       To use DPGETR or c_dpgetr, load the NCAR Graphics libraries ncarg,
43       ncarg_gks, and ncarg_c, preferably in that order.
44

MESSAGES

46       See the dashpack man page for a description of all Dashpack error
47       messages and/or informational messages.
