title: Using "String" in openCl Kernel
body: <p>I have a question about OpenCl programming. The scenario is : I have a list of words taken from a file with different length and I have to pass this list to OpenCl Kernel. I've tried to use a struct compposed by an array of char that contains the word and an int that contains the size. But this kind of solution doesn't work because, in the Kernel, I must create a new array with the size indicated in the struct, but the Kernel doesn't like arrays of variable size. There is a way to implement this solution (I mean creating one array per thread of different size)? If there is no solution in this way, how can I do?
  Thank you :) </p>
  
  <p>EDIT : This is the example code.. I hope it clarify the things</p>
  
  <pre><code>typedef struct word{
      char word[100];
      int len;
  }word_t;
  __kernel void test(__global word_t *data,  __global res_t *result)
  {
     size_t id=get_global_id(0);
     int size=0;
     size=data[id].len;
     char word[size];
     //working with the word
  
  }
  </code></pre>
  
  <p>But the clBuildProgram says that I cannot have an array with variable size.. </p>
