xiaoyafeng has asked for the wisdom of the Perl Monks concerning the following question:

Hi gurus,

I'm now interested in guts Dynaloader. Where can I find the guts doc about it(and bootstrap etc.)

I reorganize my expression, hope it can make my question more clear.

I know perl put all dll/lib files in auto directory. and use it by Dynaloader. many years, I just use it, create it by h2xs. but don't think too much about its mechanics.

Along with my C knowledge rich up, I am more and more curious :

    Dynaloader is a CPAN module, so a Google search for "cpan Dynaloader" will have the Dynaloader POD documentation as the first result. You could also get that with the command perldoc Dynaloader on a system with Perl (and Dynaloader) installed.

    You can look at the source code with the "Source" link near the top left of the CPAN web page. If you are on a Unix-like system, locate -i DynaLoader.pm should find a copy of the source code on your system.

    If you have a more specific question after looking through the source code feel free to ask.

    Both use XYZ::XS; and require XYZ::XS; load the dll in exactly the same way (by using LoadLibrary on Windows).

    The only difference (afaik) in the loading of the dll is in *when* it happens. If you use XYZ::XS; then the loading is done at script compile-time (whenever the compilation process gets to that compile-time command).
    And if you require XYZ::XS; then the loading is done at script run-time (whenever the execution process gets to that run-time command).

    Cheers,
    Rob
