DataSocket Error Codes

The following table shows the error codes that the DataSocket Library returns directly. Error codes are defined in CVIversion\toolslib\datasock\dataskt.h and <Program Files>\National Instruments\Shared\MSDTRedistributables\SDKHeaderFiles\8.1\winerror.h. Other error codes in winerror.h are generated by ActiveX servers and are passed on to you by the DataSocket Library. A negative error code indicates that the function failed.
You can use DS_GetLibraryErrorString to get the description of an error code.
