prodHeader，prodFooter和consHeader字段有什么作用？

PRODHead是生产者套接字头偏移，页脚偏移
并将消费者套接字头偏移。SDK的头文件有注释，这些注释可以提供这些文件中注释所需的这些参数的信息。
当做，

     以下为原文
  prodHeader is the producer socket header offset, prodFooter the footer offset
    and consHeader the consumer socket header offset.  The header files of the SDK have comments which provide information on these parameters you might want to have at the comment in these files.

在代码头中唯一的注释是
*生产者套接字头偏移量*/
我不确定这是否启发了我。



     以下为原文
  The only comment I see in the code for prodHeader is
    /* The producer socket header offset */
    I am not sure this in enlightening me.

要从中获取数据的偏移，即在该数据之前的数据头。
当做，
阿南德



     以下为原文
  The offset from which you want to take the data i.e. the data before that is the header.

所以说我写了这个代码
CYU3PDMACHANNEL CONFILTMYDMA；
MydMA.PudHead＝16；
…
CYU3PDMACHANNEL CREATED（ANP；句柄，CYU-U3PYDMAX Type手册，和MyDMA）；
然后提交缓冲区
CYU3PDMACHANNEL SETUPPESSEN缓冲器（和；句柄，和缓冲器）；
前16个字节不会传递给消费者，因为它们是我的头吗？
消费者报头与生产报头有什么不同？



     以下为原文
  So say I wrote this code
    CyU3PDmaChannelConfig_t myDMA;
    myDMA.prodHeader = 16;
    ...
    CyU3PDmaChannelCreate( &handle, CY_U3P_DMA_TYPE_MANUAL, &myDMA );
     
    and then submitted a buffer
    CyU3PDmaChannelSetupSendBuffer( &handle, &buffer );
    Would the first 16 bytes not be transfered to the consumer as they are my header?
    How does the consumer header differ from the producer header?

附加图像有意义吗？
在这种情况下，我们采取一个DababffER是“产生”的一些DMAChan.然后，我们将CYU3PDMACHANNETSUPUSTEnEdfRAMP称为具有其CUU3PDMACHANNEXECUTILT设置的DMAChanCub，对于PRODHOMEND、PRODHOPETER和COMPHEEADER字段具有非零值。
在PuldHead和PodFooPoT字段之间标记为“数据传输”的块是否移动到CONSEADER字段之后标记为“在何处传输数据”的区域？
我不假设PRODHead和PodPooter移动。我猜想炮兵不会受到干扰。这是正确的吗？
这是正确的解释吗？

     以下为原文
  OK does the attached image make sense?
     
    In this case we take a DMA buffer that was "produced" by some DMA channel.  We then call CyU3PDmaChannelSetupSendBuffer for a DMA channel that has its CyU3PDmaChannelConfig_t set with non zero values for the prodHeader, prodFooter, & consHeader fields. 
     
    Does the block labeled "data to transfer" between the prodHeader & prodFooter fields get moved to the area labeled "where to transfer data" after the consHeader field? 
     
    I assume none of the prodHeader, and prodFooter moves.  I assume the consHeader is not disturbed.  Is this correct?
     
    Is this the correct interpretation?
