NAME
       DPGETR - Retrieves the real value of an internal parameter of type REAL or INTEGER.


SYNOPSIS
       CALL DPGETR (PNAM,RVAL)


C-BINDING SYNOPSIS
       #include <ncarg/ncargC.h>

       void c_dpgetr (char *pnam, float *rval)


DESCRIPTION
       PNAM        (an input expression of type CHARACTER) specifies the name of the parameter to get. The name
                   must appear as the first three characters of the string.  Other characters may be used to
                   document the use of the parameter being retrieved; for example, instead of just ´LS1´, one
                   can use ´LS1 - LABEL SPACING PARAMETER 1´.

       RVAL        (an output variable of type REAL) is the name of the variable into which the value of the
                   internal parameter specified by PNAM is to be retrieved.  If the internal parameter is a
                   value "r" of type REAL, the value returned is "r".  If the internal parameter is a value "i"
                   of type INTEGER, the value returned is "REAL(i)".


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 Dashpack parameters.  For a complete list of
       parameters available in this utility, see the dashpack_params man page.


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


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