include builtins\libcurl.e
bool res = curl_loadlib(string dll_name="") |
Description: |
Optional. Allows an application to helpfully suggest and/or open (eg)
http://phix.x10.mx/pmwiki/pmwiki.php?n=Main.Libcurldlls
(windows only) or
https://curl.haxx.se/download.html
or even automatically download it (which might prove slightly difficult if you have not
already got libcurl to download things with!), or perhaps even copy it from some install
directory to the application or a system directory.
The optional dll_name parameter also allows the library name to be explicitly specified, with either a relative or absolute path, and it should, obviously, be dependent on both platform() and machine_bits(). Otherwise the library is opened automatically, but if it cannot be found then it terminates abruptly with a console message, eg "cannot open LIBCURL.32.SK.DLL". |
Example: |
include pGUI.e include builtins\libcurl.e IupOpen() if not curl_loadlib() then string txt = sprintf("cannot open %s, download from ",{curl_dll_name}), lnk = "http://phix.x10.mx/pmwiki/pmwiki.php?n=Main.Libcurldlls" Ihandle dlg = IupDialog(IupHbox({IupLabel(txt),IupLink(lnk)}, "MARGIN=10x10"),"TITLE=Error") IupPopup(dlg) abort(0) end if Note that an important point here is that libcurl is not dependent on pGUI. As shown, the global string curl_dll_name contains the actual library it tried to open. (Of course, dll_name and curl_dll_name can/should be a .so file on linux) |
