NAME

       ns_mktemp, ns_tmpnam - commands

SYNOPSIS

       ns_mktemp template

       ns_tmpnam
_________________________________________________________________

DESCRIPTION

       ns_mktemp  returns  a unique filename based on the template you specify.  ns_tmpnam returns a filename that can safely be used for a tempo-
       rary file.

       The template for ns_mktemp should contain a string with six trailing Xs, which will be replaced with an alpha-numeric string of six charac-
       ters chosen to make the filename unique.  If template does not end with six trailing Xs the empty string will be returned.

       ns_tmpnam  calls  the  tmpnam()	C  library function, and the results will depend on your operating system.  On Irix, for example, tmpnam()
       always generate a file name using the path-prefix defined as P_tmpdir in the header file which is "/var/tmp/".

EXAMPLES

	nscp> ns_tmpnam ;# On Linux
	/tmp/filevuLwaE

	nscp> ns_mktemp /tmp/foobar.XXXXXX
	/tmp/foobar.p6SlaC

NAME

       mktemp - make a unique temporary file name

SYNOPSIS

       #include <stdlib.h>

       char *mktemp(char *template);

DESCRIPTION

       The  mktemp()  function generates a unique temporary file name from template.  The last six characters of 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.

RETURN VALUE

       The  mktemp() function returns NULL on error (template did not end in XXXXXX) and template otherwise.  If the call was successful, the last
       six bytes of template will have been modified in such a way that the resulting name is unique (does not exist already).	If  the  call  was
       unsuccessful, template is made an empty string.

ERRORS

       EINVAL The last six characters of template were not XXXXXX.

CONFORMING TO

       BSD 4.3. POSIX dictates tmpnam(3).

NOTE

       The prototype is in <unistd.h> for libc4, libc5, glibc1; glibc2 follows the Single Unix Specification and has the prototype in <stdlib.h>.

BUGS

       Never  use  mktemp(). Some implementations follow BSD 4.3 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 test-
       ing whether the name exists and opening the file, every use of mktemp() is a security risk.  The race is avoided by mkstemp(3).
