Qhov tseeb, A koom tsev qiv ntawv / Dynamic Library yog a tsev qiv ntawv uas yog loaded dynamically ntawm runtime rau txhua daim ntawv thov uas xav tau nws. Lawv thauj tsuas yog ib daim ntawv luam ntawm tus tsev qiv ntawv cov ntaub ntawv hauv lub cim xeeb thaum koj khiav ib qho program, yog li ntau lub cim xeeb tau txais kev cawmdim thaum koj pib khiav ntau yam kev pab cuam uas siv qhov ntawd tsev qiv ntawv.

Tom qab ntawd, ib tug kuj yuav nug, yuav ua li cas dynamic qiv txuas?

Cov tsev qiv ntawv Dynamic yog archives ntawm binary code uas tsis yog lub cev txuas rau hauv cov ntaub ntawv executable. Cov tsev qiv ntawv yog lub cev loaded rau hauv lub computer lub cim xeeb es tsis txhob thiab thaum lub sij hawm lub kev sib txuas theem ntawm muab tso ua ke, tsuas yog qhov chaw nyob hauv lub cim xeeb ntawm lub tsev qiv ntawv muaj nuj nqi ntxiv rau hauv cov ntaub ntawv executable kawg.

Dynamic Library hauv C yog dab tsi? Static tsev qiv ntawv yog ib phau ntawm cov khoom ntaub ntawv, thaum dynamic los yog koom tsev qiv ntawv yog ib qho kev sau los ntawm cov haujlwm uas tau muab tso ua ke thiab khaws cia rau hauv ib qho kev ua tiav nrog lub hom phiaj ntawm kev sib txuas los ntawm lwm cov kev pab cuam ntawm lub sijhawm ua haujlwm. Cov tsev qiv ntawv Dynamic muab ib tug txhais tau tias siv code uas yuav tsum tau loaded nyob qhov twg hauv lub cim xeeb.

Kuj kom paub, yuav ua li cas lub tsev qiv ntawv dynamic loaded?

Dynamic loading yog ib tug mechanism uas lub computer program muaj peev xwm, thaum khiav, thauj a tsev qiv ntawv (los yog lwm yam binary) rau hauv lub cim xeeb, khaws cov chaw nyob ntawm kev ua haujlwm thiab cov hloov pauv uas muaj nyob hauv tsev qiv ntawv , ua cov haujlwm no lossis nkag mus rau cov hloov pauv, thiab tshem tawm cov tsev qiv ntawv los ntawm kev nco.

Cov tsev qiv ntawv zoo li qub thiab dynamic yog dab tsi?

Cov tsev qiv ntawv zoo li qub , thaum reusable nyob rau hauv ntau yam kev pab cuam, raug kaw rau hauv ib qho kev pab cuam ntawm compile lub sij hawm. Dynamic , los yog cov tsev qiv ntawv sib koom ntawm qhov tod tes, muaj nyob raws li cov ntaub ntawv cais tawm sab nraud ntawm cov ntaub ntawv executable. Piv txwv li, a dynamic tsev qiv ntawv tuaj yeem hloov kho yam tsis tas yuav rov sau dua.
