Primary CSV Return Codes

sv_state_check: The verb did not execute because it was issued in an invalid state.

sv_cancelled: This code is returned for an asynchronous verb when it has been shut down by a WinCSVCleanup call.

sv_file_already_exists: When the SV_NEW file option was used, the file name specified was the name of an existing file.

sv_output_device_full: There is insufficient space on the device where the output file resides. Retry the operation after freeing additional disk space.

sv_thread_blocking: This verb exceeds the maximum number of simultaneous synchronous verbs allowed.

sv_invalid_verb_segment: The VCB extended beyond the end of the data segment.

sv_unexpected_dos_error

One of the following conditions occurred:

The Microsoft® Windows NT®, Microsoft® Windows® 95, Windows version 3.x, Microsoft® MS-DOS®, or OS/2 system encountered an error while processing the verb. The operating system return code was returned through the secondary return code. If the problem persists, contact the system administrator for corrective action.
A CSV was issued from a message loop that was invoked by another application issuing a Windows environment SendMessage function call, rather than the more common Windows environment PostMessage function call. Verb processing cannot take place.
A CSV was issued when SendMessage invoked your application. You can determine whether your application has been invoked with SendMessage by using the InSendMessage Windows API function call.

sv_comm_subsystem_not_loaded: A required component could not be loaded or has terminated while processing the verb. Thus, communication could not take place. Contact the system administrator for corrective action.

sv_server_resource_not_found: No communication server was found that could provide the requested function.

sv_server_resource_lost: The communications server that was providing the function was lost due to a connection failure.

sv_invalid_verb: The opcode parameter did not match the operation code of any verb. No verb executed.
