open() and friends (like temporaryfile) does not document 'e' letter in second arguement. At least on Linux, it opens file with O_CLOEXEC.
Not sure under Windows.

Also, there are other interesting letters (man -a fopen), like:

c (since glibc 2.3.3)
       Do not make the open operation, or  subsequent  read  and  write operations, thread cancellation points.
e (since glibc 2.7)
       Open  the  file  with  the O_CLOEXEC flag.  See open(2) for more information.
m (since glibc 2.3)
       Attempt to access the file using mmap(2), rather than I/O system calls  (read(2),  write(2)).   Currently, use of mmap(2) is only attempted for a file opened for reading.

x      Open the file exclusively (like the O_EXCL flag of open(2)).  If the  file  already exists, fopen() fails, and sets errno to EEXIST.  This flag is ignored for fdopen().
