SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG_INIT function

The SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG_INIT function initializes a SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure.

Syntax


VOID SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG_INIT(
  _Out_ SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG *Config,
  _In_  size_t                            MaximumTransferLength,
  _In_  PHYSICAL_ADDRESS                  Address,
  _In_  DMA_WIDTH                         DmaWidth,
  _In_  PCM_PARTIAL_RESOURCE_DESCRIPTOR   DmaDescriptor
);

Parameters

Config [out]

A pointer to the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure that is to be initialized.

MaximumTransferLength [in]

The value to load into the MaximumTransferLength member of the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure. For more information, see the description of this member in SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG.

Address [in]

The value to load into the DeviceAddress member of the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure. For more information, see the description of this member in SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG.

DmaWidth [in]

The value to load into the DmaWidth member of the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure. For more information, see the description of this member in SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG.

DmaDescriptor [in]

The value to load into the DmaDescriptor member of the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure. For more information, see the description of this member in SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG.

Return value

None.

Remarks

Your serial controller driver must use this function to initialize a SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG structure before passing a pointer to this structure as an input parameter to the SerCx2SystemDmaTransmitCreate method.

SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG_INIT sets the Size member of the structure to sizeof(SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG), and sets four additional members of the structure to the values supplied as input parameters to the function. The function sets the other members of the structure to zero. The driver can, if necessary, explicitly set these other members to nonzero values after the SERCX2_SYSTEM_DMA_TRANSMIT_CONFIG_INIT call.
