| 名前 | 型 | 方向 | 説明 |
|---|---|---|---|
| pSecurityDescriptor | PSECURITY_DESCRIPTOR | inoptional | 新規キューに設定するセキュリティ記述子へのポインタ。NULL可で既定のセキュリティとなる。 |
| pQueueProps | MQQUEUEPROPS* | inout | 作成するキューのプロパティ(パス名等)を格納したMQQUEUEPROPS構造体へのポインタを指定する。 |
| lpwcsFormatName | LPWSTR | outoptional | 生成されたキューのフォーマット名を受け取るワイド文字列バッファを指定する。NULL可。 |
| lpdwFormatNameLength | DWORD* | inout | 入力でバッファ文字数、出力で実際の長さを受け渡すDWORDへのポインタを指定する。 |
