Mange opgaver, der er overladt til curses, kan udf\u00f8res med notcurses (og omvendt).<\/p>\n<p>Hvad det ikke er: en kompatibel implementering af X\/Open curses eller en erstatning for ncurses p\u00e5 eksisterende systemer.<\/p>\n<p>Notcurses afviser API'en fra X\/Open Curses, der medf\u00f8lger som en del af Single UNIX Specification. Denne specifikation er l\u00e6nge for\u00e6ldet og underst\u00f8tter eksempelvis ikke funktionalitet som ikke-indekseret 24-bit farve. Som s\u00e5dan er notcurses ikke en erstatning for curses. Den er mindre b\u00e6rbar og er bestemt testet p\u00e5 f\u00e6rre hardwarekonfigurationer.<br \/>\nN\u00e5r det er muligt, bruger notcurses bibliotekt terminfo, der leveres sammen med ncurses, og drager stor fordel af dens b\u00e6rbarhed.<br \/>\nNotcurses \u00e5bner udvidede muligheder for interaktion med brugere p\u00e5 arbejdsstationer, telefoner, b\u00e6rbare computere og tablets.<\/p>\n<p>Hvorfor bruge dette ikke-standard bibliotek?<\/p>\n<ul>\n<li>\n<p>Tr\u00e5d-sikkerhed og effektiv anvendelse i multitr\u00e5dede programmer har v\u00e6ret et designhensyn fra starten.<\/p>\n<\/li>\n<li>\n<p>Et mere korrekt udformet API i forhold til X\/Open:<\/p>\n<ul>\n<li>\n<p>Eksporterede identifikatorer har et pr\u00e6fiks for at undg\u00e5 navnerumskollisioner.<\/p>\n<\/li>\n<li>\n<p>Objektfilen fra biblioteket eksporterer et minimalt s\u00e6t symboler. Hvor det er rimeligt, bruges statisk kode kun til sm\u00e5 overskrifter. Dette letter kompilatoroptimering og reducerer indl\u00e6sningstiden.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<li>\n<noindex><\/p>\n<p>Alle API'er underst\u00f8tter fra starten et universelt tegns\u00e6t (Unicode).
