.SH DESCRIPTION
-Returns a pointer to a filled in struct with information about various
-run-time features in libcurl. \fItype\fP should be set to the version of this
-functionality by the time you write your program. This way, libcurl will
-always return a proper struct that your program understands, while programs in
-the future might get an different struct. CURLVERSION_NOW will be the most
-recent one for the library you have installed:
