Macro Description:
|
||
|
|
|
||
|
|
This macro wraps calls that are expected to return ERROR_SUCCESS.
|
||
|
|
If ErrorCondition occurs, it sets the LocalStatus to the ErrorCode
|
||
|
|
passed in, calls SetLastError() to set the Last Error to ErrorCode,
|
||
|
|
and jumps to the EXIT label in the calling function
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
ErrorCondition - Expression to be tested
|
||
|
|
|
||
|
|
LocalStatus - Status variable in the calling function
|
||
|
|
|
||
|
|
ErrorCode - Win 32 error code
|
||
