Stuck with Flags :-(

[emmess0000]

Hi there,

I'm pretty new to programming MCs, but facing some issues here. Actually it should be quite simple, but unfortunately I'm completely stuck here :-D I'd like to do some routines based on the flags val, so something like this:

if (strlen(msg.flags)) { if (msg.flags == "\Seen") { MailClient.printf(msg.flags); } }

But unfortunately the condition msg.flags == "\Seen" doesn't work out. Maybe you have an idea, I've tried pretty much everything :-D

`
void printMessages(std::vector<IMAP_MSG_Item> &msgItems, bool headerOnly) {

for (size_t i = 0; i < msgItems.size(); i++) {

  IMAP_MSG_Item msg = msgItems[i];

  Serial.println("****************************");
  MailClient.printf("Number: %d\n", msg.msgNo);
  MailClient.printf("UID: %d\n", msg.UID);
  MailClient.printf("Messsage-ID: %s\n", msg.ID);

  if (strlen(msg.flags)) {
    if (msg.flags == "\Seen") {
      MailClient.printf(msg.flags);
    }
  }

  if (strlen(msg.subject)) {
    MailClient.printf(msg.subject);
  }
      
  if (strlen(msg.return_path)) {
    MailClient.printf(msg.return_path);
  }
      
  if (!headerOnly && strlen(msg.html.content)) {
    MailClient.printf(msg.html.content);
  }

}

}

String returns (output) from all result objects in this library is the pointer to const char (*const char) then using == operator for comparison is not valid C++ syntax.

You have to use C/C++ syntax strcmp.
