SCGetExpFldr
SCGetExpFldr returns information about shared folders and volumes.
Note Macintosh File Sharing does not return fnfErr when there is no shared
volume or folder at a particular index position. Instead, it returns noErr
and takes no other action. To determine if a particular location is in use,
set scVRefNum to zero before calling SCGetExpFldr. If scVRefNum is still zero
after SCGetExpFldr is called, then there is no shared volume or folder at
that particular index position.
!! WARNING SCNamePtr must be NIL when scIndex is negative. Otherwise,
Macintosh File Sharing writes garbage into memory. See the comments in the
sample function code listed under "SCGetExpFldr" in Chapter 1. !!
