c - 在 c 中使用标记化

Question

我正在尝试标记一条线并将其放入二维数组中，到目前为止我已经想出了这个，但我觉得我还很遥远:

/**
 * Function to tokenize an input line into seperate tokens
 *
 * The first arg is the line to be tokenized and the second arg points to
 * a 2-dimentional string array. The number of rows of this array should be
 * at least MAX_TOKENS_PER_LINE size, and the number of columns (i.e., length
 * of each string should be at least MAX_TOKEN_SIZE)
 *
 * Returns 0 on success and negative number on failure
 */

int __tokenize(char *line, char tokens[][MAX_TOKEN_SIZE], int *num_tokens){

char *tokenPtr;
tokenPtr = strtok(line, " \t");
    for(int j =0; j<MAX_TOKEN_SIZE; j++){
      while(tokenPtr != NULL){
        if(!(tokens[][j] = tokenPtr)){return -1;}
            num_tokens++;
            tokenPtr = strtok(NULL, " \t");
        }
    }
  return 0;
}

Answer 1

int __tokenize(char *line, char tokens[][MAX_TOKEN_SIZE], int *num_tokens)
{
char *tokenPtr;
tokenPtr = strtok(line, " \t");
for (int i = 0; tokenPtr; i++)
{
            tokens[i] = tokenPtr;
            tokenPtr = strtok(NULL, " \t");
}
}

希望这能起作用。
