Debug Notification -9 - Coprocessor Error Notification

This notification returns:

Cmd

= DBG_N_CoError
Value
= Any standard Error Code

An error was detected while attempting a DosDebug command that attempted to access a Coprocessor.

DBG_N_CoError is similar to the DBG_N_Error notification, but is returned only after attempting an access to the coprocessor registers.

DBG_N_CoError is returned if any one of the following occurs:

• The debuggee process is emulating the coprocessor. 
  The specified debuggee thread has not yet attempted to use the coprocessor.
  
  The wrong coprocessor type is used.
  
  The requested coprocessor type is not supported or available.

  This notification should not be confused with any of the floating point exception notifications.
