I dunno how relevant the Open Group's "Single UNIX ® Specification,
Version 2" is as a standards document, but it simply says that mktemp()
takes an argument with 6 X's in it and replaces each X with a single
byte character from the portable filename character set.
It does say, however, "If a unique name cannot be created, [mktemp
returns] a null string"; ("null string" means "", not NULL). Although
mktemp() clearly needs to read the directory in order to ensure that
the name is unique, it's also fairly clear that if the directory
doesn't exist then the name is unique.
