Return Values VSCMD_RequestQuery returns:
•VSE_TRUE
- Successful execution if the API is operating in
synchronous mode
- Good initial status received if the API is operating in
asynchronous mode
•VSE_FALSE - The request failed. A return code of
VSE_FALSE (which is 0) means the request failed.
- To determine where the error occurred, and what the
error was, the client queries the request’s error handle
(with VS_Error_GetFields) to retrieve the error
handle’s object code.
- If the object code’s value is VSE_NONE, the client
must query the global error code (VSG_Error) to
determine where the error occurred.
•VSE_ERR_BADHANDLE - Specified handle was not a valid
command handle.
•VSE_ERR_NULLHANDLE - Specified handle was a null
pointer.
VSID_USER_FIELD (VST_USER_FIELD) The value to put in USER_FIELD for this
request. USER_FIELD is a 16-character field
provided for user information. Information
entered in this field is echoed back to the user
in every status message returned for this
request. Neither the API software nor VolServ
uses USER_FIELD.
