Utimens Event

Fires when the OS needs to change access and modification times of a file.

Syntax

• C++

ANSI (Cross Platform)
virtual int FireUtimens(FUSEUtimensEventParams *e);

typedef struct {
  const char *Path;
  int FileContext;
  int64 ATime;
  int64 MTime;
  int Result;
  int reserved;
} FUSEUtimensEventParams;

Unicode (Windows)
virtual INT FireUtimens(FUSEUtimensEventParams *e);

typedef struct {
  LPCWSTR Path;
  INT FileContext;
  LONG64 ATime;
  LONG64 MTime;
  INT Result;
  INT reserved;
} FUSEUtimensEventParams;

#define EID_FUSE_UTIMENS 24

virtual INT CBFSFUSE_CALL FireUtimens(LPWSTR &lpszPath, INT &iFileContext, LONG64 &lATime, LONG64 &lMTime, INT &iResult);

Remarks

This event fires when the OS needs to change access and modification times of the file, identified by either Path or FileContext. The ATime and MTime parameters contain the access time and modification time respectively. All date/time parameters in the class are specified as a number of 100-nanosecond intervals since Jan 1, 1601 00:00:00 UTC (Windows) or as a number of seconds since Jan 1, 1970 00:00:00 UTC (Linux)

To convert the values of the ATime and MTime parameters to Unix time, FileTimeToUnixTime method.

The ATimeNS and MTimeNS parameters contain the subsecond part of the ATime and MTime date/time value respectively, counted in nanoseconds.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a negative error code value (e.g. -ENOENT to indicate that the file does not exist) to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
