c - Weird seg faults on consecutive calls to the same array -


I've really worked hard to find a solution on this but I can not think enough keywords.

Currently I'm having trouble with the concept behind makinggings and it is used with triple pointers (I do not know whether *** Afu means it is easy as a concept Is not ** foo or * foo). So I created my own: 

  const char ** makeargv (char * string, int * numargs) {string = string + strspn (string, delims); Four * copy = maulok (string (string) + 1); Int i; Strcpy (copy, string); Int notebooks; If (strtok (copy, delims)! = NULL) {for (numtokens = 1; strtok (NULL, delims)! = NULL; numtokens ++} {}} strcpy (copy, string); Const char * Results [numtokens + 1]; Results [0] = Stroke (copy, Dalmis); For (i = 1; i

This is where it breaks: 

  void parse_file (char * filename) {char * line = malloc (160 * sizeof () Char)); File * fp = file_open (filename); Int i = 0; Int digit = 0; Int * Notifier = & amp; Numargs; While ((line = file_gateline (line, fp)) = null) {if (strangle (line) == 1) {continue; } Const char ** args = makeargv (line, indicator); Printf ("% s \ n", args [0]); Printf ("% s \ n", args [1]); / * It prints the RGS [0], but then the reasoning [1] causes the SEG fault even if I change ARG [1] with any other argument [0], then it is still Also causes a mistake / fclose (fpose); free line); }

I have an array of strings working. However, when I try to print the wire in the array, I can only print 1 of my choice and then make this mistake for any subsequent call. IRG [3] = {"yes", "no", "may be"}, if I say argv [0], then it will let me say "yes", but any other call (even if i then argv [0]) does not work and is due to a segfault. I can call any element from the array, but once I call one, the work is finished to work.

Please help? D: It's in C. 

  const char * result [numtokens + 1];

This array "result" is a local variable, it is only available within "macaragua".

You want to use a better malloc: 

  result = malloc (numtokens + 1)

and I believe That your code has a memory leak, you will not be able to free up memory for "four * copy" 

  four = copy = maulok (string) + 1);

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
