Nyob rau hauv C Programming Language, realloc muaj nuj nqi yog siv los hloov qhov thaiv ntawm lub cim xeeb uas tau muab faib ua ntej. Lub luag haujlwm realloc faib ib lub cim xeeb (uas tuaj yeem ua rau nws loj dua lossis me dua qhov loj dua qhov qub) thiab luam cov ntsiab lus ntawm lub qub block rau lub cim xeeb tshiab, yog tias tsim nyog.
Yuav ua li cas koj rov muab lub cim xeeb?
Qhov loj ntawm kev faib cov cim xeeb tuaj yeem hloov pauv los ntawm kev siv realloc. Raws li tus qauv C99: voidrealloc (voidptr, size_t loj); realloc deallocates cov khoom qub taw qhia los ntawm ptr thiab xa rov qab tus taw tes rau ib yam khoom tshiab uas muaj qhov loj me uas tau teev tseg los ntawm qhov loj me.
Qhov twg yog siv los tso lub cim xeeb?
free function yog siv los tso lub cim xeeb uas yog dynamically reserved rau blocks & uas yog tsis xav tau. Syntax: void free(void block); Nws tso qhov thaiv ntawm tus taw tes qhia.
Kev nco qhov chaw yog dab tsi?
Thaum ib qho kev sim ua kom hloov pauv qhov tsis sib xws los ntawm kev hu mus rau lub luag haujlwm realloc, tus taw tes raug kuaj xyuas kom siv tau yog tias nws tsis yog tus nqi NULL. Yog tias nws siv tau, lub header ntawm lub heap tsis yog kuaj xyuas kom pom tseeb. Tus thawj tsis yog ces tso tawm. …
Kev ua haujlwm twg tso lub cim xeeb tsis tsim nyog?
