Hi, as I am a developer using Visual Basic programming language, I cannot take part in this post on posting and sharing the C++ codes on downloading file, including image and document file. I can demonstrate how to download file, for example, how to download image file from url at the very beginning of an image reading and processing project. level 1. xieem. Op · 9m. update when sshing I get. [error] bltadwin.ru_file_download (): curl_easy_perform () failed: Couldn't resolve host name. after doing cat /tmp/bltadwin.ru I noticed that I don't have DNS. bltadwin.ru=enabled. bltadwin.rurverstatus=disabled. bltadwin.rurverstatus=disabled. /* in this example, file_size must be an curl_off_t variable */ curl_easy_setopt(easyhandle, CURLOPT_INFILESIZE_LARGE, file_size); When you call curl_easy_perform this time, it will perform all the necessary operations and when it has invoked the upload it will call your supplied callback to get the data to upload.
