i write simple program when run program, if not root user, input root password, change uid root if (getuid()) { char *pass = getpass(""); //how change uid root ? } how change uid root when got root password? there no way change non-root user root. that's whole point. programs login , sshd , or su work starting root , either because of ancestry or having suid bit on executable file, , restricting can until authenticate password or other method, changing appropriate uid (either root or user you're logging in as) , exec 'ing program (usually, shell).

when error occurs, c code store error before exiting program. advised store stderr file (e.g., /home/logs.txt) or advised use different method keep logs/error report (considering programming environment linux ). e.g., code below, how apply method store logs/error message on /home/log.txt or /home/log file *fp1; fp1 = fopen("/sys/class/gpio/export","w"); if(fp1 == null){ fprintf(stderr, "errno:%s - opening gpio136 failed - line 739\n ", strerror(errno)); close(fp1); exit(1); } thank you. if stderr used print out error message, so, can redirect output specific file. $ program 2>~/logs.txt for better logging tool, can use: syslog standard function. log4c library.

i'm writing code decision tree in c. right gives me correct result (0% training error, low test error), takes long time run. the problem lies in how run qsort. basic algorithm this: every feature sort feature column using qsort remove duplicate feature values in column every unique feature value split determine entropy given split save best feature split + split value every training_example if training_example's value best feature < best split value, store in left[] else store in right[] recursively call function, using left[] training examples recursively call function, using right[] training examples because last 2 lines iterative calls, , because tree can extend dozens , dozens of branches, number of calls qsort huge (especially dataset has > 1000 features). my idea reduce runtime create 2d array (in separate function) each column sorted feature column. then, long maintain vector
