Question

1|few ewf ew fewfew 

I need to parse it but I don't know how can I drop whitespaces tail from second value I don't know.

Here is my segmentation fault try so far

char* token1;
char* token2;
char* search = "|";
char* search2 = "  "; // double space because string can contains single space
while (fgets(line, 150, f)) {
  token1 = strtok(line, search);
  token2 = strtok(search, search2); // <- segfault
  //token2 = strtok(NULL, search); <- contains a lot of spaces in tail

Take a gander at the deblank function. Here's a link: http://www.mathworks.com/help/matlab/ref/deblank.html
