NAME

       ixp_srv_walkandclone, ixp_srv_readdir, ixp_srv_verifyfile, IxpLookupFn

SYNOPSIS

       #include <ixp_srvutil.h>

       void ixp_srv_walkandclone(Ixp9Req *req, IxpLookupFn lookup);

       void ixp_srv_readdir(Ixp9Req *req, IxpLookupFn lookup, void (*dostat)(IxpStat *, IxpFileId *));

       bool ixp_srv_verifyfile(IxpFileId *file, IxpLookupFn lookup);

       typedef IxpFileId* (*IxpLookupFn)(IxpFileId*, char*);

DESCRIPTION

       These  convenience  functions  simplify the writing of basic and static file servers. They
       use a generic file lookup function to  simplify  the  process  of  walking,  cloning,  and
       returning  directory  listings.  Given the IxpFileId(3) of a directory and a filename name
       should return  a  new  IxpFileId  (allocated  via  ixp_srv_getfile(3))  for  the  matching
       directory  entry,  or null if there is no match. If the passed name is null, lookup should
       return a linked list of IxpFileIds, one for each child directory entry.

       ixp_srv_walkandclone handles the moderately complex process of walking  from  a  directory
       entry  and  cloning  fids,  and calls ixp_respond(3). It should be called in response to a
       TWalk request.

       ixp_srv_readdir should be called to handle read requests on  directories.  It  prepares  a
       stat  for each child of the directory, taking into account the requested offset, and calls
       ixp_respond(3). The dostat parameter must be a function which fills the passed  IxpStat(3)
       pointer based on the contents of the passed IxpFileId.

       ixp_srv_verifyfile  returns  whether  a file still exists in the filesystem, and should be
       used by filesystems that invalidate files once they have been deleted.
