Get the last token out of wchar_t*

I have a wchar_t* in my C code, that contains URL in the following format:

https://example.com/test/...../abcde12345

I want to split it by the slashes, and get only the last token (in that example, I want to get a new wchar_t* that contains "abcde12345").

How can I do it?

Thank you?

Solution

  • In C, you can use wcsrchr to find the last occurence of /:

    #include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <wchar.h>
int main(void){
  wchar_t *some_string = L"abc/def/ghi";

  wchar_t *last_token = NULL;
  wchar_t *temp = wcsrchr(some_string, L'/');
  if(temp){
    temp++;
    last_token = malloc((wcslen(temp) + 1) * sizeof(wchar_t));
    wcscpy(last_token, temp);
  }

  if(last_token){
    wprintf(L"Last token: %s", last_token);
  }else{
    wprintf(L"No / found");
  }
}
