SECPKG_EXTRA_OIDS

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 44 バイト / x86: 44 バイト

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)。

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)
; SECPKG_EXTRA_OIDS サイズ: 44 バイト(x64)
dim st, 11    ; 4byte整数×11(構造体サイズ 44 / 4 切り上げ)
; OidCount : DWORD (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; Oids : SECPKG_SERIALIZED_OID (+4, 40byte)  varptr(st)+4 を基点に操作(40byte:入れ子/配列)
; ※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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
#defstruct global SECPKG_SERIALIZED_OID
    #field int OidLength
    #field int OidAttributes
    #field byte OidValue 32
#endstruct

#defstruct global SECPKG_EXTRA_OIDS
    #field int OidCount
    #field SECPKG_SERIALIZED_OID Oids 1
#endstruct

stdim st, SECPKG_EXTRA_OIDS        ; NSTRUCT 変数を確保
st->OidCount = 100
