UT_ERR0/UT_WERSY - Vector $CA

This vector writes an error message to channel 0.

Call ParameterReturn Parameter
D0.LError codeD0.LPreserved.

No errors are returned by this vector call.

  • All registers not shown above are not used on entry and are preserved on exit.
  • This vector can be used in supervisor mode.
  • If D0.L is positive no action is taken. Otherwise the error message corresponding to the value in D0.L is sent to channel 0 with timeout 0. If this fails an attempt is made to send the message to channel $00010001.

The example below shows how to use this vector. D0.L is assumed to contain the error code.
