peek 音标拼音: [p'ik] vi. 偷看,窥视
n. 偷看,窥见 偷看,窥视偷看,窥见 peek取数 peek n 1: a secret look [ synonym: { peek}, { peep}] v 1: throw a glance at; take a brief look at; " She only glanced at the paper"; " I only peeked-- I didn' t see anything interesting" [ synonym: { glance}, { peek}, { glint}] Peek \ Peek\ ( p[= e] k), v. i. [ OE. piken: cf. F. piquer to pierce, prick, E. pique. Cf. { Peak}.] To look surreptitiously, or with the eyes half closed, or through a crevice; to peep. [ Colloq.] [ 1913 Webster] 24 Moby Thesaurus words for " peek": bend the eyes, blink, cast, direct the eyes, flash, gander, glance, glimpse, half an eye, look, meddle, nose, peep, peer, play peekaboo, pry, quick sight, rapid glance, slant, snoop, spy, squiz, take a peep, winkThe command in most { microcomputer} { BASICs} for reading
memory contents ( a byte) at an absolute address. POKE is the
corresponding command to write a value to an absolute address.
This is often extended to mean the corresponding constructs in
any { High Level Language}.
Much hacking on small { microcomputers} without { MMUs} consists
of " peek" ing around memory, more or less at random, to find
the location where the system keeps interesting stuff. Long
( and variably accurate) lists of such addresses for various
computers circulate ( see { interrupt list}). The results of
" poke" s at these addresses may be highly useful, mildly
amusing, useless but neat, or total { lossage} ( see { killer
poke}).
Since a { real operating system} provides useful, higher- level
services for the tasks commonly performed with peeks and pokes
on micros, and real languages tend not to encourage low- level
memory groveling, a question like " How do I do a peek in C?"
is diagnostic of the { newbie}. Of course, { operating system}
{ kernels} often have to do exactly this; a real { C} hacker
would unhesitatingly, if unportably, assign an absolute
address to a pointer variable and indirect through it.

( 1995- 01- 31) Partners Early Experience Kit ( Taligent) peek: n., vt. ( and poke) The commands in most microcomputer BASICs for directly accessing memory contents at an absolute address; often extended to mean the corresponding constructs in any HLL ( peek reads memory, poke modifies it). Much hacking on small, non- MMU micros used to consist of peeking around memory, more or less at random, to find the location where the system keeps interesting stuff. Long ( and variably accurate) lists of such addresses for various computers circulated. The results of pokes at these addresses may be highly useful, mildly amusing, useless but neat, or ( most likely) total lossage ( see killer poke). Since a real operating system provides useful, higher- level services for the tasks commonly performed with peeks and pokes on micros, and real languages tend not to encourage low- level memory groveling, a question like “ How do I do a peek in C?” is diagnostic of the newbie. ( Of course, OS kernels often have to do exactly this; a real kernel hacker would unhesitatingly, if unportably, assign an absolute address to a pointer variable and indirect through it.)
