I tried adding a section to your attached code to have it write to a file if the object wasn't named control.empeg. I added this segment:

        if(strcmp(name, "control.empeg") == 0)

                empeg_command(body);

        else {

                strcpy(filename, "/tmp/");

                strcat(filename, name);

                printf("Write it to a file.\n");

                if(tempfd = open(filename, O_WRONLY) > 0 ) {

                        printf("Writing to '%s' (%d)\n", filename, tempfd);

                        write(tempfd, body, strlen(body));

                        close(tempfd);

                }

        }

but I'm obviously doing something wrong... the call to open() returns an fd of 1 so I write to stdout instead of the file. Can you see what I did wrong?
