DspExport overview

DspExport works as follows:

  • When it receives a socket connection request, it establishes a connection to the radar server computer (RVP10SRV) and initially allows multiple connections.

  • DspExport handles the INFO, SETUP, and OPEN commands.

  • When the OPEN command is sent, an exclusive connection for I/O to RVP10SRV is established.

    If a second OPEN request arrives while the first is still active, it fails, and returns the message Device allocated to another user.

The source code and examples for DspExport and the dsp library are provided with the RVP release software. DSP Files
Example File
DspExport ${IRIS_ROOT}/src/rda/dsp
dsp library ${IRIS_ROOT}/base/dsp_lib

In the library, the example codetalks to DspExport in the OpenSocket.c, dsp_read.c, and dsp_write.c files.

tip Search for the string SOCKET to see how the code differs between SCSI interface and socket interface.
