シグネチャ

// certpoleng.dll
#include <windows.h>

NTSTATUS PstGetCertificateChain(
    const CERT_CONTEXT* pCert,
    SecPkgContext_IssuerListInfoEx* pTrustedIssuers,

パラメーター

名前	型	方向	説明
pCert	CERT_CONTEXT*	in	チェーンを構築する起点となる証明書のCERT_CONTEXTへのポインタ。
pTrustedIssuers	SecPkgContext_IssuerListInfoEx*	in	信頼された発行者リストを示す構造体へのポインタ。チェーン構築の基準とする。
ppCertChainContext	CERT_CHAIN_CONTEXT**	out	構築された証明書チェーンコンテキストへのポインタを受け取る出力ポインタ。
