Bool_t TAlienSystem::AccessPathName ( const char *  path, EAccessMode  mode = kFileExists  )

virtual

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

The file name must not contain any special shell characters line ~ or $, in those cases first call ExpandPathName(). Attention, bizarre convention of return value!!

Reimplemented from TSystem.

Definition at line 406 of file TAlienSystem.cxx.

int TAlienSystem::AlienFilestat ( const char *  fpath, 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.
