DBG_N_CoError

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.
