.SH NAME

|
libcurl-easy \- easy interface overview
|
|
.SH DESCRIPTION
|
|
When using libcurl's "easy" interface you init your session and get a handle
|
|
(often referred to as an "easy handle"), which you use as input to the easy
|
|
interface functions you use. 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 as you may have figured out yourself). You might want
|
|
to set some callbacks as well that will be called from the library when data
|
|
is available etc. \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 will help 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 almost 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 will then do the entire operation and will 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.
