「C」言語での SMTP および POP3 アクセスに libetpan-1.0 オープン ソース (メール ライブラリのもの) を使用しています。SMTP と POP3 の SSL 接続に問題があります。SSL 接続を確立して接続に失敗すると、ソケットが CLOSE_WAIT 状態のままになります。これにより、長時間の後にメモリ リークが発生します。コマンド「netstat -an」の出力は次のとおりです。このアプリケーションを ARM ボードで実行しています。誰が私に何をすべきか教えてもらえますか? 前もって感謝します。
Here is my code that i am trying.
pSmtp = mailsmtp_new(0, NULL); (Create new object)
if (SMTP_NO_ERROR != mailsmtp_ssl_connect(pSmtp, "smtp.gmail.com", 465))
{
mailsmtp_free(pSmtp);
}
else
{
// Send Mail
}
So doesn't my work is over after i call function "mailsmtp_free(pSmtp)" or
i have do other stuff to close connection.
~#netstat -an
