24 * - Array[h] -- Access to the character array
26 * - Array[h*w] -- Attribute array
27 * - Array[h*w] -- Character array
29 * Note that the attr/char pair at (x,y) is a[y][x]/c[y][x]
30 * and that the row of attr/chars at (0,y) is a[y]/c[y]

243 * Definitions for the "actions" of "Term_xtra()"
245 * These values may be used as the first parameter of "Term_xtra()",
246 * with the second parameter depending on the "action" itself. Many
247 * of the actions shown below are optional on at least one platform.
249 * The "TERM_XTRA_EVENT" action uses "v" to "wait" for an event
250 * The "TERM_XTRA_SHAPE" action uses "v" to "show" the cursor
251 * The "TERM_XTRA_FROSH" action uses "v" for the index of the row
252 * The "TERM_XTRA_SOUND" action uses "v" for the index of a sound
253 * The "TERM_XTRA_ALIVE" action uses "v" to "activate" (or "close")
254 * The "TERM_XTRA_LEVEL" action uses "v" to "resume" (or "suspend")
255 * The "TERM_XTRA_DELAY" action uses "v" as a "millisecond" value
257 * The other actions do not need a "v" code, so "zero" is used.
