CPGETR(3NCARG)

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

SYNOPSIS
CALL CPGETR (PNAM, RVAL)

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

void c_cpgetr (char *pnam, float *rval)

DESCRIPTION

PNAM
    (CHARACTER, input) is the name of a parameter whose real value is to be retrieved. Only the first three characters of PNAM are examined. It is recommended that the rest of the character string be used to improve the readability of the code. For example, instead of just 'SFS', use 'SFS - SCALE FACTOR SELECTOR'.

RVAL
    (REAL, output) is a variable in which the value of the parameter specified by PNAM is to be returned. 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 Conpack parameters. For a complete list of parameters available in this utility, see the conpack_params man page.

EXAMPLES
Use the ncargex command to see the following relevant examples: ccpclc, ccpklb, ccpllt, colcon, cpex01, cpex06, cpex07, cbex01.

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

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