Use \fIcurl_easy_init(3)\fP to get the handle. You continue by setting all the options you want in the upcoming transfer, the most important among them is the URL itself (you cannot transfer anything without a specified URL). You might want to set some callbacks as well that are called from the library when data is available etc. For example \fICURLOPT_WRITEFUNCTION(3)\fP. \fIcurl_easy_setopt(3)\fP is used for all this. \fICURLOPT_URL(3)\fP is the only option you really must set, as otherwise there can be no transfer. Another commonly used option is \fICURLOPT_VERBOSE(3)\fP that helps you see what libcurl is doing under the hood, which is useful when debugging for example. The \fIcurl_easy_setopt(3)\fP man page has a full index of the over 300 available options. If you at any point would like to blank all previously set options for a single easy handle, you can call \fIcurl_easy_reset(3)\fP and you can also make a clone of an easy handle (with all its set options) using \fIcurl_easy_duphandle(3)\fP. When all is setup, you tell libcurl to perform the transfer using \fIcurl_easy_perform(3)\fP. It performs the entire transfer operation and does not return until it is done (successfully or not). After the transfer has been made, you can set new options and make another transfer, or if you are done, cleanup the session by calling \fIcurl_easy_cleanup(3)\fP. If you want persistent connections, you do not cleanup immediately, but instead run ahead and perform other transfers using the same easy handle. .SH SEE ALSO .BR curl_easy_cleanup (3), .BR curl_easy_init (3), .BR curl_easy_setopt (3), .BR libcurl (3), .BR libcurl-errors (3), .BR libcurl-multi (3)
