Imibuzo Evame Ukubuzwa

Iyini i-defer ku-C futhi isebenza kanjani ku-gcc ne-clang?

I-Defer iwumshini okuvumela ukuthi uhlele ikhodi yokuhlanza ukuthi isebenze ngokuzenzakalela uma isikophu siphuma, kungakhathaliseki ukuthi siphuma kanjani. Igqugquzelwa izilimi ezifana ne-Go kanye ne-Zig, i-defer ku-gcc ne-clang isebenzisa izandiso ze-compiler ukuqinisekisa ukuthi izinsiza ezifana nememori, izibambo zefayela, nezingidi zikhishwa ngokufanelekile. Lokhu kuqeda iziphazamisi ezivamile zokuvuza kwensiza futhi kwenza ikhodi C iphephe ngokuphawulekayo futhi inakekeleke ngaphandle kokudinga ukuhlanzwa mathupha kuzo zonke izindawo ezibuyayo.

Iziphi izinguqulo ze-gcc ne-clang support ezihlehlisayo?

Usekelo lwe-Defer lwethulwe ngezandiso eziqondene nomhlanganisi kanye neziphakamiso ezihambisana nokuthuthukiswa kwesimanje kwe-C. I-GCC kanye noClang basebenzise ukusebenza okufana ne-defer ngokusebenzisa izibaluli zokuhlanza kanye neziphakamiso zolimi ezintsha. Onjiniyela kufanele bahlole imibhalo yabo yomdidiyeli ukuthola izimfuneko zenguqulo eziqondile. Ukuhlala unolwazi ngezibuyekezo ze-compiler kuqinisekisa ukufinyelela kulezi zici ezinamandla ezenza lula ukuphathwa kwensiza kumaphrojekthi we-C.

Ukuhlehlisa kuthuthukisa kanjani ukuphepha kwekhodi C uma kuqhathaniswa nokuhlanza mathupha?

Ukuhlanza mathupha ku-C kunephutha — onjiniyela kufanele bakhumbule ukukhulula izinsiza kuzo zonke izindawo zokuphuma, okuhlanganisa nezindlela zamaphutha. I-Defer yenza lokhu ngokuzenzakalelayo ngokubophezela ukuhlanzwa ngokuqondile ekuphumeni kwesikophu, ukunciphisa ukuvuza kwememori kanye neziphazamisi zokuqeda izinsiza. Emaqenjini akha izinhlelo zokusebenza eziqinile, ukuhlanganisa i-defer nokugeleza komsebenzi okuhleliwe kunganciphisa ngokumangazayo izilinganiso zokukhubazeka. I-Mewayz inikeza amamojula angu-207 ngo-$19/mo asiza onjiniyela basebenzise imikhuba emihle yesimanje kuwo wonke amaphrojekthi abo.

Ingabe ukuhlehlisa kungasetshenziswa eduze kwamaphethini akhona okuphatha isisetshenziswa C?

Yebo, i-defer ihlanganisa ngokushelelayo namaphethini akhona afana nezisonga zesitayela se-RAII, ukuhlanza okusekelwe ku-goto, namakholi amahhala mathupha. Ungakwazi ukuhlehlisa kancane kancane ku-codebase yakho ngaphandle kokuphinda ubhale ikhodi ekhona. Isebenza kahle ikakhulukazi emisebenzini emisha kanye nokwenza kabusha ingqondo yokuhlanza ifa. Onjiniyela abahlola amathuluzi esimanje C kanye nokusebenza okuzenzakalelayo kokugeleza komsebenzi bangasebenzisa izinkundla ezifana ne-Mewayz, ehlinzeka ngamamojula angu-207 alungele ukusetshenziswa aqala ku-$19/mo ukuze kuqondiswe izinqubo zentuthuko.
