EVT_SEEK_FLAGS enumeration (winevt.h)

  • Makale

Defines the relative position in the result set from which to seek.

Syntax

typedef enum _EVT_SEEK_FLAGS {
  EvtSeekRelativeToFirst = 1,
  EvtSeekRelativeToLast = 2,
  EvtSeekRelativeToCurrent = 3,
  EvtSeekRelativeToBookmark = 4,
  EvtSeekOriginMask = 7,
  EvtSeekStrict = 0x10000
} EVT_SEEK_FLAGS;

Constants

 
EvtSeekRelativeToFirst
Value: 1
Seek to the specified offset from the first entry in the result set. The offset must be a positive value.
EvtSeekRelativeToLast
Value: 2
Seek to the specified offset from the last entry in the result set. The offset must be a negative value.
EvtSeekRelativeToCurrent
Value: 3
Seek to the specified offset from the current entry in the result set. The offset can be a positive or negative value.
EvtSeekRelativeToBookmark
Value: 4
Seek to the specified offset from the bookmarked entry in the result set. The offset can be a positive or negative value.
EvtSeekOriginMask
Value: 7
A bitmask that you can use to determine which of the following flags is set:


  • EvtSeekRelativeToFirst

  • EvtSeekRelativeToLast

  • EvtSeekRelativeToBookmark
EvtSeekStrict
Value: 0x10000
Force the function to fail if the event does not exist.

Remarks

If the offset or bookmark seeks past the boundary of the result set (past the first or last record), and EvtSeekStrict is not set, seek will return the last record within the boundary.

If the bookmark is within the boundaries of the result set (based on event record ID) but is not included in the result set, the seek function will apply the offset relative to the bookmark's record ID. In the following table, the first column shows the record IDs of the events in the result set. If the bookmark's record ID is 3989, the second column shows the record that the seek function would seek to given the specified offset.

Record ID Offset
3995 –2
3991 –1
3987 0, 1
3983 2
3979 3
3975 4
3971 5
3968 6
3959 7
3955 8
