ncl_argetr: Retrieves the real value of an Areas parameter.

NAME

ARGETR - Retrieves the real value of an Areas parameter.

SYNOPSIS

CALL ARGETR (PNAM,RVAL)

C-BINDING SYNOPSIS

#include <ncarg/ncargC.h>

void c_argetr (char *pnam, float *rval)

DESCRIPTION

PNAM

(an input constant or variable of type CHARACTER) - The name of the parameter that you want to retrieve. The character string can be of any length, but only the first two characters of it will be examined.

RVAL

(an output variable of type REAL) - A real variable to receive the desired parameter value. If the internal parameter is of type REAL and has the value "r", RVAL will be given the value "r"; if the internal parameter is of type INTEGER and has the value "i", RVAL will be given the value "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 Areas parameters. For a complete list of parameters available in this utility, see the areas_params man page.

ACCESS

To use ARGETR or c_argetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

MESSAGES

See the areas man page for a description of all Areas error messages and/or informational messages.
