Member Function Documentation

autoStat()

int XrdSsiDir::autoStat ( struct stat *  buf )

virtual

Set the stat() buffer where stat information is to be placed corresponding to the directory entry returned by nextEntry().

Returns

If supported, SFS_OK should be returned. If not supported, then SFS_ERROR should be returned with error.code set to ENOTSUP.

Note

: When autoStat() is in effect, directory entries that have been deleted from the target directory are quietly skipped.

Reimplemented from XrdSfsDirectory.

{
   const char *epname = "autoStat";
 
// Check if this directory is actually open
//
   if (dirP) return dirP->autoStat(buf);
   return XrdSsiUtils::Emsg(epname, EBADF, epname, "???", error);
}

Here is the call graph for this function:

close()

int XrdSsiDir::close ( )

virtual

Close the directory.

Returns

One of SFS_OK or SFS_ERROR

Implements XrdSfsDirectory.

Definition at line 120 of file XrdSsiDir.cc.

{
   const char *epname = "closedir";
 
// Close as needed
//
   if (dirP) return dirP->close();
   return XrdSsiUtils::Emsg(epname, EBADF, epname, "???", error);
}

copyError()

void XrdSsiDir::copyError ( XrdOucErrInfo &  einfo )

inline

Definition at line 48 of file XrdSsiDir.hh.

{einfo = error;}

References XrdSfsDirectory::error.

FName()

const char * XrdSsiDir::FName ( )

virtual

Get the directory path.

Returns

Null terminated string of the path used in open().

Implements XrdSfsDirectory.

Definition at line 164 of file XrdSsiDir.cc.

{
   const char *epname = "fname";
 
// Check if this directory is actually open
//
   if (dirP) return dirP->FName();
   XrdSsiUtils::Emsg(epname, EBADF, epname, "???", error);
   return "";
}

References XrdSsiUtils::Emsg(), XrdSfsDirectory::error, and XrdSfsDirectory::FName().

Here is the call graph for this function:

nextEntry()

const char * XrdSsiDir::nextEntry ( )

virtual

Get the next directory entry.

Returns

A null terminated string with the directory name. Normally, "." ".." are not returned. If a null pointer is returned then if this is due to an error, error.code should contain errno. Otherwise, error.code should contain zero to indicate that no more entries exist (i.e. end of list). See autoStat() for additional caveats.

Implements XrdSfsDirectory.

   const char *epname = "readdir";
 
// Get next directory entry if we can
//
   if (dirP) return dirP->nextEntry();

Here is the call graph for this function:

open()

int XrdSsiDir::open ( const char *  path, const XrdSecEntity *  client, const char *  opaque = 0  )

virtual

Open a directory.

Parameters

path	- Pointer to the path of the directory to be opened.
client	- Client's identify (see common description).
opaque	- path's CGI information (see common description).

Returns

One of SFS_OK, SFS_ERROR, SFS_REDIRECT, ir SFS_STALL
