[rrd-users] C API problem (rrd_update)

[Dustin Sallings]

	I've got an application that receives temperature data from
various parts of my network via multicast and I'd like to store this into
rrd.  I stumbled across the C API, and it looks easy enough, so I figured
I'd give it a go.

	If I understand it correctly, I feed the same thing I'd feed into
``rrdtool -'' and it should just go, however, it's reporting an error
on each update after the first:

update file.rrd -t 10C8892A00000096 1011763371:20.940001
OK
update file.rrd -t 10E8C214000000E4 1011763404:14.180000
ERROR:  opening '10E8C214000000E4': No such file or directory
        args[0]=``update''
        args[1]=``file.rrd''
        args[2]=``-t''
        args[3]=``10E8C214000000E4''
        args[4]=``1011763404:14.180000''
update file.rrd -t 1081841E000000DF 1011763405:17.030001
ERROR:  opening '1081841E000000DF': No such file or directory
        args[0]=``update''
        args[1]=``file.rrd''
        args[2]=``-t''
        args[3]=``1081841E000000DF''
        args[4]=``1011763405:17.030001''
[etc...]

	If I have it just output the command and feed it into rrdtool -,
it works just fine (well, it doesn't like there being more than one update
per second when it happens, but that's a fairly easy problem to deal with
once I get to it).

	It seems to be handling the commandline incorrectly after the
first call.

	Here's the calling code (buf is the command that's being printed
out):

    args=split(buf, " ");
    rv=rrd_update(listLength(args), args);
    if(rv<0 || rrd_test_error()) {
        int i=0;
        printf("ERROR:  %s\n", rrd_get_error());
        for(i=0; i<listLength(args); i++) {
            printf("\targs[%d]=``%s''\n", i, args[i]);
        }
        rrd_clear_error();
    } else {
        printf("OK\n");
    }
