delphi - TStream.Position compared to TStream.Seek -

-

to move "current byte" pointer in tstream class can use property position (e.g. mystream.position := 0) or using seek method (e.g. mystream.seek(0, sofrombeginning). question is, 1 more efficient (aka faster)? (i don't have source, not check myself).

so far use seek in positioning said pointer.

as tstream.seek overloaded function handling 32-bit or 64-bit values, depends on current stream implementation, might better choice.

for instance tcustommemorystream implements 32-bit version of seek(). when set position on stream first call 64-bit version, casts value longint while calling 32-bit version. (this change 64-bit version of delphi!)

on other hand thandlestream implements 64-bit version of seek(). when call seek() 32-bit value end in quite nasty mechanism calling 64-bit version.

my personal advice set position. @ least better choice in future.

c++ - Compiling static TagLib 1.6.3 libraries for Windows -

i having super hard time compiling , using taglib 1.6.3 in qt project. i've tried can think of. taglib claims supported through cmake i'm not having luck. furthermore, i'm confused kinds of files need qt libs! i've built *.a files, *.lib, , *.dll. understand far... believe since i'm working in windows *.lib want. no matter do, end "undefined references" taglib functions try use when try compile qt project. have tried mingw32, msys, visual studio 2008, , cross-compiling windows on linux. turning nothing. what makes less sense me if compile same taglib source qt on mac (g++ think?) works fine! somewhere in windows compilation procedures have going wrong. have been smacking face on desk 30 (on , off) hours trying figure out. since qt uses mingw must compile taglib same compiler? if compile *.lib's visual studio not compatible? are *.a libraries usable in windows? (assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
