Function

Vipstracked_open

Declaration [src]

int
vips_tracked_open (
  const char* pathname,
  int flags,
  int mode
)

Description [src]

Exactly as open(2), but the number of files currently open via vips_tracked_open() is available via vips_tracked_get_files(). This is used by the vips operation cache to drop cache when the number of files available is low.

You must only close the file descriptor with vips_tracked_close().

pathname should be utf8.

See also: vips_tracked_close(), vips_tracked_get_files().

	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`flags`	`int`
	Flags for `open()`
`mode`	`int`
	Open mode.

Return value

Returns:	`int`
	A file descriptor, or -1 on error.
