Hi all,

I'm trying to parse each line of a comma delimited file into an array.
The file uses quotation marks to contain strings.

I can break each string into an array using "strtok", but, it fails
whenever the comma delimiter is contained within quotation marks.

For example, here's an input line from the csv file:
"this is a phrase",23, "more stufF"

which I break into an array
a[0] = "this is a phrase"
a[1] = 23
a[2] = "more stufF"

My function works okay with that input until the special case of a
comma appearing within a quoted string, eg:
"this is a phrase",23, "more stufF", "John, Bill, and Bob"

which gives me
a[0] = "this is a phrase"
a[1] = 23
a[2] = "more stufF"
a[3] = "John
a[4] = Bill
a[5] = and Bob"

instead of
a[0] = "this is a phrase"
a[1] = 23
a[2] = "more stufF"
a[3] = "John, Bill, and Bob"

which is what I wanted.

Here's how I was trying to do it:
char **split_text(char *string,char *token, int *count)
{
char **retval = NULL;
char *ptr = NULL;
*count = 0;
ptr = strtok(string,token);
while(ptr != NULL)
{
*count = *count + 1;
retval = (char**)realloc(retval,(*count * sizeof(char*)));
retval[*count - 1] = strdup(ptr);
ptr = strtok(NULL,token);
}
return retval;
}

which won't work because the strtok gives me no opportunity to mention
a delimiter AND token. I need something that takes advantage of regexp,
I guess, but hopefully, there's a common or popular routine for this.

Can someone tell me how to do this the efficient way?

Thanks!
