Unnamed temporary files [3.11]
+
+ -
+ Open directory with option O_TMPFILE to create an
+ unnamed temporary file on that filesystem
+
+ -
+ As with tmpfile(), the file disppears on
+ last close()
+
+ -
+ File can be linked into the filesystem using
+ linkat(..., AT_EMPTY_PATH), allowing for 'atomic'
+ creation of file with complete contents and metadata
+
+ -
+ Not supported on all filesystem types, so you will usually need
+ a fallback
