Thread: Tokenizing Command Line Arguments

Hi,

I am working on a tokenizer for command line arguments, to eventually work in a mini shell program. I cannot use strtok, I must get the arguments by hand. I have to ignore tokens that are in quotation marks.

For example:
cd ls "test"

token 0 - cd
token 1 - is
token 2 - "test"

So I was thinking that if I had a pair of starting quotes, then I would advance the i counter until i hit the pair of ending quotes, then put that info into the token. Here is what I have that is definitely not working. Any ideas on what direction I am going, or not going in? Any guidance would be appreciated. Thanks.

Code:

struct token* tokenizer(char* __commandline,int* __argumentcounter)
{
  /*the following data structure should hold all the tokens*/
  struct token* tokenlist = malloc(sizeof(struct token));

		int i = 0;
		int j = 0;
		/*struct token* head = tokenlist;*/
		struct token tokstruct;
		struct token *tok;
		tok = &tokstruct;
		while (__commandline[i] != '\n')
		{
			if(__commandline[i] == '\"')
      
			{
				i++;
				if(__commandline[i] == '\"')
				{
					tok*[j] = __commandline[i];
					j++;
				}
   
				else if(__commandline[i] == ' ')
				{
					i++;
				}
			}
		}
