TMPDIR temporary directory path.

## Description

The `TMPDIR` constant holds the temporary directory absolute path of a Scilab process. Each Scilab process has its own temporary directory, created and referenced to `TMPDIR` during Scilab startup. The temporary directory is deleted when Scilab stops.

The temporary directories are created as subdirectories of the system temporary directory and named SCI_TMP_<unique> where <unique> is some number generated at Scilab startup for the name to be unique. Under GNU/Linux, UNIX and Mac OS X, directory access rights are limited to the Scilab user.

The `TMPDIR` constant cannot be altered during Scilab execution. However, under GNU/Linux, UNIX and Mac OS X, the system temporary directory (usually `/tmp`) can be selected by altering the `TMPDIR` system variable.

`dirname(TMPDIR)` can be used as a general temporary directory, without respect to any Scilab session.

## Examples

    ls TMPDIR
    ls(TMPDIR)
    cd(TMPDIR)
