HCD_STAT_COUNTERS

構造体

サイズx64: 24 バイト / x86: 24 バイトパッキング1

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド	型	サイズ	x64	x86	説明
BytesTransferred	DWORD	4	+0	+0	ホストコントローラで転送された総バイト数。
IsoMissedCount	WORD	2	+4	+4	スケジュールに間に合わずミスしたアイソクロナス転送の回数。

CrcErrorCount	WORD	2	+8	+8	CRCエラーの発生回数。
ScheduleOverrunCount	WORD	2	+10	+10	スケジュールオーバーランの発生回数。
TimeoutErrorCount	WORD	2	+12	+12	タイムアウトエラーの発生回数。
InternalHcErrorCount	WORD	2	+14	+14	ホストコントローラ内部エラーの発生回数。
BufferOverrunErrorCount	WORD	2	+16	+16	バッファオーバーランエラーの発生回数。
SWErrorCount	WORD	2	+18	+18	ソフトウェアエラーの発生回数。
StallPidCount	WORD	2	+20	+20	STALL PIDを受信した回数。エンドポイント停止を示す。

HSP用定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)

dim st, 6    ; 4byte整数×6(構造体サイズ 24 / 4 切り上げ)
; BytesTransferred : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; IsoMissedCount : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; DataOverrunErrorCount : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; CrcErrorCount : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; ScheduleOverrunCount : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)

; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。

; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
