Recommend a C or C++ code to send a basic email using the SMTP protocol

@2kaud do you know if getting the code to compile in VS IDE will also compile in a JNI implementation?

Sorry, no. I only use VS.

As far as I know, JNI stands for Java Native Interface. So, the question is: why would anybody need SMTP be coded in C/C++, when there must be lots of Java packages doing the same, but natural Java way?

Because VS IDE automatically sets up the required correct build environment and uses the correct options with cl to compile the program - whereas Netbeans IDE isn't.

@2kaud , I finally got the code above to compile using your pre-requisite header information and variables for the new c++ standard. I also am not using Netbeans IDE, instead I am using Microsoft Visual Studio. I also did not realize it was not a '.c' file but a '.cpp' file. After the code is compiled run the command "SENDMAIL.exe smtp.gmail.com [email protected] [email protected] message.txt"
<p>where I include text in the 'message.txt'.
<p> The result of the program is 'Sent message.txt as email message to [email protected]'
<p> but when I check my outbox and inbox the message sent from the c++ program is not there.
<p> I know that the program connects to the internet, because when I disconnect my wifi and run the program I get "Cannot find SMTP mail server smtp.gmail.com"
<p> What can I do now to test the email being sent?
<p> Finally shouldn't the c++ program include login(username,password) to authenticate with gmail? like the "PasswordAuthentication"-Session variable in this example: https://www.tutorialspoint.com/javam...mple_email.htm

I needed this for an Android implementation as an alternate to not being able to find working library examples for the javamail example. Got the javamail working, but now I want to learn about the C/C++ implementation.
