XMLPUBFUN xmlChar* XMLCALL xmlPathToURI ( const xmlChar * path )

xmlPathToURI: : the resource locator in a filesystem notation

Constructs an URI expressing the existing path

Returns a new URI, or a duplicate of the path parameter if the construction fails. The caller is responsible for freeing the memory occupied by the returned string. If there is insufficient memory available, or the argument is NULL, the function returns NULL.
