Function Reference
— Built-in Function: [fid, name, msg] = mkstemp (template, delete)

Return the file ID corresponding to a new temporary file with a unique name created from template. The last six characters of template must be XXXXXX and these are replaced with a string that makes the filename unique. The file is then created with mode read/write and permissions that are system dependent (on GNU/Linux systems, the permissions will be 0600 for versions of glibc 2.0.7 and later). The file is opened with the O_EXCL flag.

If the optional argument delete is supplied and is true, the file will be deleted automatically when Octave exits, or when the function purge_tmp_files is called.

If successful, fid is a valid file ID, name is the name of the file, and msg is an empty string. Otherwise, fid is -1, name is empty, and msg contains a system-dependent error message.
