StorPortRegistryWrite function (storport.h)

  • Artikel

The StorPortRegistryWrite routine is called by the miniport driver to convert the registry data contained in a specified buffer from ASCII to Unicode and to then write the data to the miniport driver's per-HBA storage area.

Syntax

STORPORT_API BOOLEAN StorPortRegistryWrite(
  [in] PVOID  HwDeviceExtension,
  [in] PUCHAR ValueName,
  [in] ULONG  Global,
  [in] ULONG  Type,
  [in] PUCHAR Buffer,
  [in] ULONG  BufferLength
);

Parameters

[in] HwDeviceExtension

A pointer to the hardware device extension. This is a per HBA storage area that the port driver allocates and initializes on behalf of the miniport driver. Miniport drivers usually store HBA-specific information in this extension, such as the state of the HBA and the mapped access ranges for the HBA. This area is available to the miniport driver immediately after the miniport driver calls StorPortInitialize. The port driver frees this memory when it removes the device. The miniport driver must be running at IRQL PASSIVE_LEVEL when it calls this routine.

[in] ValueName

Pointer to a string that specifies the value name.

[in] Global

Indicates whether the operation is to be adapter specific or to relate to all adapters.

[in] Type

One of the following registry data types.

Type Meaning
REG_SZ Unicode null-terminated string.
REG_EXPAND_SZ Unicode null-terminated string with environment variable references.
REG_BINARY Binary data.
REG_DWORD 32-bit double word.
REG_DWORD_LITTLE_ENDIAN 32-bit double word with a little-endian format.
REG_DWORD_BIG_ENDIAN 32-bit double word with a big-endian format.
REG_LINK Unicode string that specifies a symbolic link.
REG_MULTI_SZ Multiple Unicode strings.
REG_RESOURCE_LIST Resource list in the resource map.
REG_FULL_RESOURCE_DESCRIPTOR Resource list in the hardware description.
REG_RESOURCE_REQUIREMENTS_LIST Resource requirement list.
REG_QWORD 64-bit quadlet number.
REG_QWORD_LITTLE_ENDIAN 64-bit quadlet number with a little-endian format.

[in] Buffer

Pointer to a buffer that contains the registry data to be written.

[in] BufferLength

Specifies the size of the buffer pointed to by Buffer.

Return value

StorPortRegistryWrite returns a Boolean value of TRUE if the registry data was successfully converted and written; otherwise, this routine returns FALSE.
