<function>realpath</function> expands all symbolic links and
|
|
resolves references to '/./', '/../' and extra '/' characters in
|
|
the input <parameter>path</parameter> and return the canonicalized
|
|
absolute pathname. The resulting path will have no symbolic link,
|
|
'/./' or '/../' components.

<para>

<function>realpath</function> returns &false; on failure, e.g. if

the file does not exist. On BSD systems <function>realpath</function>
|

doesn't fail if only the last <parameter>path</parameter> component
|

doesn't exist, while other systems will return &false;.
