Member Function Documentation

Bool_t THDFSSystem::AccessPathName ( const char *  path, EAccessMode  mode  )

virtual

Returns FALSE if one can access a file using the specified access mode.

Mode is the same as for the Unix access(2) function. Attention, bizarre convention of return value!!

Reimplemented from TSystem.

Definition at line 482 of file THDFSFile.cxx.

void THDFSSystem::FreeDirectory ( void *  dirp )

virtual

Free directory via httpd.

Reimplemented from TSystem.

Definition at line 395 of file THDFSFile.cxx.

const char * THDFSSystem::GetDirEntry ( void *  dirp )

virtual

Get directory entry via httpd. Returns 0 in case no more entries.

Reimplemented from TSystem.

Definition at line 416 of file THDFSFile.cxx.

Int_t THDFSSystem::GetPathInfo ( const char *  path, FileStat_t &  buf  )

virtual

Get info about a file.

Info is returned in the form of a FileStat_t structure (see TSystem.h). The function returns 0 in case of success and 1 if the file could not be stat'ed.

Reimplemented from TSystem.

Definition at line 454 of file THDFSFile.cxx.

Int_t THDFSSystem::MakeDirectory ( const char *  name )

virtual

Make a directory.

Reimplemented from TSystem.

Definition at line 342 of file THDFSFile.cxx.

void * THDFSSystem::OpenDirectory ( const char *  path )

virtual

Open a directory via hdfs.

Returns an opaque pointer to a dir structure. Returns 0 in case of error.

Reimplemented from TSystem.

Definition at line 361 of file THDFSFile.cxx.

Int_t THDFSSystem::Unlink ( const char *  path )

virtual

Unlink, i.e.

remove, a file or directory. Returns 0 when successful, -1 in case of failure.

Reimplemented from TSystem.

Definition at line 502 of file THDFSFile.cxx.
