This function synchronizes <parameter>stream</parameter> contents to storage media, just like <function>fsync</function> does,
|
|
but it does not synchronize file meta-data.
|
|
Note that this function is only effectively different in POSIX systems.
|
|
In Windows, this function is aliased to <function>fsync</function>.
