Retrieves the real value of an internal parameter of type real or integer.
CALL DPGETR (PNAM,RVAL)
#include <ncarg/ncargC.h>
void c_dpgetr (char *pnam, float *rval)
(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\'.
(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)".
The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
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.
To use DPGETR or c_dpgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
See the dashpack man page for a description of all Dashpack error messages and/or informational messages.
