Debug Notification -1 - Error Notification

This notification returns:

Cmd

= DBG_N_Error
Value
= Any standard error code

An error was detected while attempting a DosDebug command.

Error codes are returned from DosDebug in different ways:

• Errors can be returned via the standard method (EAX = ERROR_CODE).

  This is only done when the DosDebug command failed to execute at all. An example of this would be ERROR_INTERRUPT when the debugger receives a signal. If DosDebug returns a nonzero value in the EAX register, the returned Debug buffer is invalid.

• Errors are also returned via the DBG_N_Error notification.

  This is used when the DosDebug command was attempted, but failed due to some internal DosDebug failure. Examples of error codes returned via this interface are ERROR_INVALID_PROCID and ERROR_INVALID_DATA. Generally, these errors are detected while in the context of the debuggee process, and may include ERROR_INTERRUPT.
