parsing - Processing C command line arguments -


how process multiple command line arguments in package manager? giving shot @ writing package manager , right accepting packages install giving me quite headache. example user wants install package x,y , z. right code send 3 different requests function. package names in 1 go. example, user wants install package x,y , z, processed , code send request function stating needs x,y , z , function begin work immediately.

here's current implementation...

case 's':     switch (argv[1][2]) {         case 'u':             id = 1;             alfred("system", "update", "", id);             break;          case 'r':             id = 1;             alfred("system", "reload", "", id);             break;          case 'i':             if (argc - 2 != 0) {                 // loop until packages complete.                 packages = 2; // starting point of packages = argv[2][0]                 srand(time(null)); // seed random number                 id = rand(); // generate random number id                 argc = argc - 2 + 1; // argc minus number of packages , plus 1                 /* inefficent loop! */                 /* must targets , feed alfred */                 while (packages <= argc) {                     alfred("system", "install", &argv[packages][0], id);                     packages++;                 }             } else {                 printf("unrecognized format. execute alfred -h more information.\n");             }             break;          default:             printf("unrecognized format. execute alfred -h more information.\n");             break;     }     break;

you can try libargtable. used before parse various arguments, it's handy.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
