Use of BSA_DataBlock32 in BSASendData()
For BSASendData(), all parameters in the BSA_DataBlock32 structure are set by the XBSA application and adhere to the NetBackup XBSA interface preferences or the function fails with a BSA_RC_INVALID_DATABLOCK error. The NetBackup XBSA interface is not allowed to change any of the parameters.
The buffers that are passed by BSASendData() must be full. This means that numBytes must be equal to bufferLen. The buffer for the last BSASendData() call for an object does not need to be full.
