To transfer files, you create an "easy handle" using \fIcurl_easy_init(3)\fP
for a single individual transfer (in either direction). You then set your
-desired set of options in that handle with \fIcurk_easy_setopt(3)\fP. Options

you set with \fIcurl_easy_setopt(3)\fP stick. They will be used on every
repeated use of this handle until you either change the option, or you reset
them all with \fIcurl_easy_reset(3)\fP.
capability via the GNU TLS library, there is an elaborate tree inside

-\fIcurl_global_init()\fP is the function that you must call. This may

-The basic rule for constructing a program that uses libcurl is this:
-Call \fIcurl_global_init()\fP, with a \fICURL_GLOBAL_ALL\fP argument,
-immediately after the program starts, while it is still only one
-thread and before it uses libcurl at all. Call
-\fIcurl_global_cleanup()\fP immediately before the program exits, when
-the program is again only one thread and after its last use of
-libcurl.

You can call both of these multiple times, as long as all calls meet
these requirements and the number of calls to each is the same.
know whether they use libcurl or not. And its code doesn't necessarily
run at the start and end of the whole program.
-A module like this must have global constant functions of its own,
-just like \fIcurl_global_init()\fP and \fIcurl_global_cleanup()\fP.
-The module thus has control at the beginning and end of the program
-and has a place to call the libcurl functions. Note that if multiple
-modules in the program use libcurl, they all will separately call the
-libcurl functions, and that's OK because only the first
-\fIcurl_global_init()\fP and the last \fIcurl_global_cleanup()\fP in a
-program change anything. (libcurl uses a reference count in static
-memory).

-situation by defining a special class that represents the global
-constant environment of the module. A program always has exactly one
-object of the class, in static storage. That way, the program
-automatically calls the constructor of the object as the program
-starts up and the destructor as it terminates. As the author of this
-libcurl-using module, you can make the constructor call
-\fIcurl_global_init()\fP and the destructor call
-\fIcurl_global_cleanup()\fP and satisfy libcurl's requirements without
-your user having to think about it.

-\fIcurl_global_init()\fP has an argument that tells what particular
-parts of the global constant environment to set up. In order to
-successfully use any value except \fICURL_GLOBAL_ALL\fP (which says to
-set up the whole thing), you must have specific knowledge of internal
-workings of libcurl and all other parts of the program of which it is
-part.

-A special part of the global constant environment is the identity of
-the memory allocator. \fIcurl_global_init()\fP selects the system
-default memory allocator, but you can use \fIcurl_global_init_mem()\fP
-to supply one of your own. However, there is no way to use
-\fIcurl_global_init_mem()\fP in a modular program -- all modules in
-the program that might use libcurl would have to agree on one
-allocator.
-
-There is a failsafe in libcurl that makes it usable in simple
-situations without you having to worry about the global constant
-environment at all: \fIcurl_easy_init()\fP sets up the environment
-itself if it hasn't been done yet. The resources it acquires to do so
-get released by the operating system automatically when the program

This failsafe feature exists mainly for backward compatibility because
there was a time when the global functions didn't exist. Because it
