パラメーター

名前型方向説明
virtualPathLPCWSTRin仮想的に見せるパス(バインドリンクのマッピング元)を指す文字列。
backingPathLPCWSTRinvirtualPathの実体となる背後のパスを指す文字列。
createBindLinkFlagsCREATE_BIND_LINK_FLAGSinバインドリンク作成時の動作を制御するフラグ(CREATE_BIND_LINK_FLAGS)。読み取り専用やマージなどを指定する。
exceptionCountDWORDinexceptionPaths配列に含まれる除外パスの数。
exceptionPathsLPCWSTR*inoptionalマッピングから除外するパスの配列へのポインタ。除外がなければNULL可。
