// Contents: IIS Pathname Parser
|
|
//
|
|
// The Pathname Parser is a key component in ADs providers. It checks for
|
|
// syntactic validity of an ADs pathname that has been passed to this
|
|
// provider. If the syntax is valid, then an OBJECTINFO structure is
|
|
// constructed. This OBJECTINFO structure contains a componentized version
|
|
// of the ADs pathname for this object.
|
|
//
|
|
// Note all that is being done is a syntax check. Rather than special-case
|
|
// every single new nuance to pathnames, all path checking must conform to
|
|
// the grammar rules laid out by the parser.
