Section (1) mktemp
mktemp — create a temporary file or directory
Create a temporary file or directory, safely, and print
its name. TEMPLATE must contain at least 3 consecutive _zsingle_quotesz_X_zsingle_quotesz_s
in last component. If TEMPLATE is not specified, use
−−tmpdir is implied. Files are
created u+rw, and directories u+rwx, minus umask
create a directory, not a file
do not create anything; merely print a name (unsafe)
suppress diagnostics about file/dir−creation failure
append SUFF to TEMPLATE; SUFF must not contain a slash. This option is implied if TEMPLATE does not end in X
interpret TEMPLATE relative to DIR; if DIR is not specified, use $TMPDIR if set, else
/tmp/. With this option, TEMPLATE must not be an absolute name; unlike with
−t, TEMPLATE may contain slashes, but mktemp creates only the final component
interpret TEMPLATE as a single file name component, relative to a directory: $TMPDIR, if set; else the directory specified via

mktemp — make a unique temporary filename
Never use this function; see BUGS.
generates a unique temporary filename from
template. The last six
template must be XXXXXX and
these are replaced with a string that makes the filename
unique. Since it will be modified,
template must not be a string
constant, but should be declared as a character array.
mktemp() function always
a unique name was created, the last six bytes of
template will have been
modified in such a way that the resulting name is unique
(i.e., does not exist already) If a unique name could not be
made an empty string, and
is set to indicate the error.
For an explanation of the terms used in this section, see attributes(7).
implementations follow 4.3BSD and replace XXXXXX by the
current process ID and a single letter, so that at most 26
different names can be returned. Since on the one hand the
names are easy to guess, and on the other hand there is a
race between testing whether the name exists and opening the
file, every use of
a security risk. The race is avoided by mkstemp(3) and mkdtemp(3).
