6 IDGETR - Retrieves the real value of a Bivar parameter.

9 CALL IDGETR (PNAM,RVAL)

12 #include <ncarg/ncargC.h>
13
14 void c_idgetr (char *pnam, float *rval)
15
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
30 The C-binding argument descriptions are the same as the FORTRAN
31 argument descriptions.
32
34 This routine allows you to retrieve the current value of Bivar
35 parameters. For a complete list of parameters available in this
36 utility, see the bivar_params man page.
37
39 To use IDGETR or c_idgetr, load the NCAR Graphics libraries ncarg,
40 ncarg_gks, and ncarg_c, preferably in that order.
41
43 See the bivar man page for a description of all Bivar error messages
44 and/or informational messages.
