QUESTION
I am downloading csv file from AWS S3 bucket so that I can use it in D3.
No problem downloading the csv file. In code below the console.log(data.Body.toString())
prints out the csv file contents in expected format
However, I am not sure how to pass the downloaded csv file content to D3 in code below.
The file contents are already in nice csv file format.
Question: how to replace merged.csv
below with the mergedcsv
object?
ANSWER
Answered 2019-Jul-12 at 00:23After reading a the docs on d3.csv, it loads a CSV file from a URL, but in your example, you've already loaded the data, you just need to parse it. So d3.csv isn't going to be of any use.
It looks like the D3 function for parsing is d3.csv.parse(data)
which will return an array of parsed data. (Docs are here)
So you could do something like…
QUESTION
typedef struct S {
int i;
char *pc;
} S;
void foo() {
char str[] = "abcdefg";
const S cs = {1, str};
// more code
}
...ANSWER
Answered 2017-Nov-12 at 05:13const char *ptr
: means ptr should point to same address, you can't expect ptr to hold some other address.
cs.pc
is nothing but const char *pc
, So while passing it to function
void foo_a(const char * * ppcc);
// will not work bcz ppcc can point to any address
thats why you should use option B
