Perhatikan bahwa output debugger mungkin berisi campuran objek ACX publik seperti ACXMANAGER, ACXCIRCUITFACTORY, dan ACXCIRCUIT dan struktur internal yang didefinisikan buram. Jenis internal tidak dijamin tetap sama, atau tersedia dalam rilis ACX yang berbeda, dan tidak boleh dipanggil atau digunakan secara langsung.
Karena objek ACX adalah objek WDF, Anda dapat menggunakan perintah !wdfkd.wdfhandle untuk menampilkan informasi tambahan tentang objek ACXMANAGER.

Contoh panduan driver ACX
Bagian ini menyediakan panduan penelusuran kesalahan driver ACX.
Jalur simbol
Gunakan .symfix dan perintah .sympath (Atur Jalur Simbol) untuk mengubah jalur simbol. Jika Anda menggunakan kode lokal dengan driver, tambahkan jalur ke kode tersebut juga. Gunakan perintah .reload (Reload Module) untuk memuat ulang simbol dari jalur saat ini.
.symfix
.sympath+ C:\Windows-driver-samples-develop\audio\Acx\Samples\AudioCodec\Driver
.reload /f
Konteks debugger untuk driver
Jika Anda menelusuri kesalahan driver ACX aktif, atur titik henti. Ini menempatkan debugger dalam konteks objek ACX, untuk dapat mengumpulkan dan menampilkan informasi.
Contoh titik henti ini dirancang untuk diaktifkan saat driver AudioCodec sampel dimulai.
bm AudioCodec!DriverEntry
bm AudioCodec!AcxDriverInitialize
Contoh titik henti ini dirancang untuk diaktifkan ketika tindakan tertentu terjadi, seperti pembuatan pin atau sirkuit.
bm AudioCodec!AcxPinCreate
bm AudioCodec!AcxCircuitCreate
bm AudioCodec!Codec_EvtBusDeviceAdd
Setelah driver dimuat dan titik henti yang sesuai telah diaktifkan, dan konteks eksekusi yang valid tersedia, gunakan perintah !acxkd untuk menampilkan informasi tentang objek ACX apa pun. Gunakan perintah !acxobject untuk informasi umum dan perintah tertentu, seperti !acxcircuit atau !acxpin untuk informasi yang lebih terperinci.
Memuat dll acxkd
Gunakan perintah .load (Load Extension DLL) untuk memuat ekstensi acxkd.dll.
.load acxkd.dll
Menampilkan informasi tentang pengandar ACX
Untuk mengumpulkan informasi tentang driver target, gunakan perintah lm (List Loaded Modules) untuk melihat semua driver yang dimuat. Kemudian gunakan opsi Dvm untuk menampilkan informasi tentang driver ACX yang menarik seperti yang ditunjukkan di sini.
