fopen fails in my capp

When you use fopen in a Capp you must specify the entire path for the file. If you do not do this the the fopen will fail when you start the capp from the task manager or download because the default path is write protected. Will not work. fp = fopen("tmp.txt", "w"); if(fp == NULL) { return(0); } Will work. fp = fopen("/var/ftp/usrflash/Project/tmp.txt", "w"); if(fp == NULL) { return(0); }
