AccessPathName()

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!!
