NAME

6       ARGETR - Retrieves the real value of an Areas parameter.
7

SYNOPSIS

9       CALL ARGETR (PNAM,RVAL)
10

C-BINDING SYNOPSIS

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

DESCRIPTION

17       PNAM        (an input constant or variable of type CHARACTER) - The
18                   name of the parameter that you want to retrieve.  The
19                   character string can be of any length, but only the first
20                   two characters of it will be examined.
21
22       RVAL        (an output variable of type REAL) - A real variable to
23                   receive the desired parameter value.  If the internal
24                   parameter is of type REAL and has the value "r", RVAL will
25                   be given the value "r"; if the internal parameter is of
26                   type INTEGER and has the value "i", RVAL will be given the
27                   value "REAL(i)".
28

C-BINDING DESCRIPTION

30       The C-binding argument descriptions are the same as the FORTRAN
31       argument descriptions.
32

USAGE

34       This routine allows you to retrieve the current value of Areas
35       parameters. For a complete list of parameters available in this
36       utility, see the areas_params man page.
37

ACCESS

39       To use ARGETR or c_argetr, load the NCAR Graphics libraries ncarg,
40       ncarg_gks, and ncarg_c, preferably in that order.
41

MESSAGES

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