Member Function Documentation

close()

int XrdSfsNativeDirectory::close ( )

virtual

Close the directory.

Returns

One of SFS_OK or SFS_ERROR

Implements XrdSfsDirectory.

   static const char *epname = "closedir";

Here is the caller graph for this function:

FName()

const char* XrdSfsNativeDirectory::FName ( )

inlinevirtual

Get the directory path.

Returns

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

Implements XrdSfsDirectory.

Definition at line 57 of file XrdSfsNative.hh.

{return (const char *)fname;}

nextEntry()

const char * XrdSfsNativeDirectory::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.
