A secure tmpfile() replacement
This is the secure replacement for tmpfile() that does not exist in GLIBC. It uses the Linux specific O_TMPFILE
and O_EXCL
to hide the filename. When the FILE
is fclose()'ed, the file contents is lost. The file is hidden in the _PATH_TMP
("/tmp") directory in the system.
This function requires Linux 3.11, or later, due to O_TMPFILE
. Not all file systems support hidden inodes, in which case this function defaults to call tmpfile() as a fallback.
