            do
            {
                fgets(strget,244,arq);


                if(strcmp(str,strtok(strget,"")) == 0)//teste para achara a palavar no arquivo
                {

            }while(!feof(arq) || strcmp(str,strtok(strget,"")) != 0 );//teste se ha a frase dentro do arquivo ate acabar o arq

        }while( dir != NULL);//testa todo os arq do dir mencionado

  • What’s the matter with you?

  • I need the user to type a directory to search in it one or two (in another code) words and so display the directory files that have these words..!

  • I have another code that it uses two words but stop tests and parameters for STRTOK() are bugged

  • I did not ask what the task was as a whole, but what specific problem is preventing you from completing this task. If I didn’t express myself well before, now I hope I’ve been straight to the point

  • is summarized in the third loop and the parameter for Strtok(), because you pass the string read from Arq to Strtok() as it is the same in the loop?

  • this problem could not solve...

You need to call Strtok the first time before entering the third loop.

token = strtok(strget, "");

Inside the third loop, you must call passing NULL as parameter:

token = strtok(NULL, "");
