dce quagga 1.7 file access problem

[bright....@gmail.com]

hi, everyone

I got a problem when I'm using dce quagg 1.7.

When I write this code in my dce application code, 

    if((fp = fopen("/home/test/1w3e.txt", "wt"))==NULL){

        printf("fopen error\n");

        exit(1);

    }

    fprintf(fp, "Hello world!");

    fclose(fp);

I always get a NULL pointer from fopen function, but in real environment, it works well.

Has anyone come across this before?

Thanks!

dce does some kind of chrooting in "files-X/" folders (with X the node id). Thus you should copy your file in one such folder.

it doesn't work, though.

I run

 touch files-5/home/test/1w3e.txt

and run waf again,but the file 1w3e.txt is still blank.

try to look with a debugger what could happen, put a breakpoint on
dce_fopen is defined in dce-stdio.cc. what is the "t" in "wt" , it
doesn't appear in the manpage. SHouldn't it be a "+" ?
