Temporary files: RAM or disk?Temporary files: RAM or disk?Posted Jun 4, 2012 16:44 UTC (Mon) by dgm (subscriber, #49227)In reply to: Temporary files: RAM or disk? by dvdeug Parent article: Temporary files: RAM or disk?
Linux does not interpret C semantics. Linux implements POSIX semantics, and C programs use POSIX calls to access those semantics. So this has nothing to do with C, but POSIX.
POSIX offers a tool to make sure your data is safely stored: the fsync() call. POSIX and the standard C library are careful not to make any promises regarding the reliability of writes, because this would mean a burden for all systems implementing those semantics, some of which do not even have a concept of fail-proof disk writes.
Now Linux could chose to deviate from the standard, but that would be exactly the reverse of portability, wouldn't it?
