bs = BYTES
quab yuam ibs = BYTES thiab obs = BYTES
cbs = BYTES
hloov BYTES bytes ntawm ib lub sijhawm
conv = KEYWORDS
hloov cov ntaub ntawv raws li tus voj voos ntawm cov ntawv sau tseg
suav = BLOCKS
luam xwb BLOCKS input blocks
ibs = BYTES
nyeem BYTES bytes ib zaug
yog = NTSUAB
nyeem ntawm cov ntaub ntawv ua siv stdin
obs = BYTES
sau BYTES bytes ib zaug
ntawm = PHEEJ YWG
sau ntawv rau cov ntaub ntawv tsis txhob stdout
nrhiav = BLOCKS
hla BLOCKS obsized blocks ntawm pib ntawm cov zis
hla = tawg
