  22 // Short overview over the debug output macros:
  23 //      PRINT()
  24 //              is for general messages that very unlikely should appear in a release build
  25 //      FATAL()
  26 //              this is for fatal messages, when something has really gone wrong
  27 //      INFORM()
  28 //              general information, as disk size, etc.
  29 //      REPORT_ERROR(status_t)
  30 //              prints out error information
  31 //      RETURN_ERROR(status_t)
  32 //              calls REPORT_ERROR() and return the value
  33 //      D()
  34 //              the statements in D() are only included if DEBUG is defined
