Routine Description:
 
    Common Driver Frameworks DbgBreakPoint() function.
 
    This will only break point if WdfVerifierDbgBreakOnError is defined, so
    it's safe to call for production systems.
 
Arguments:
 
    DriverGlobals -
 
Return Value:
 
    None.

Routine Description:
 
    Common Driver Frameworks KeBugCheckEx() function. Use this function rather
    than the system one. This routine will indicate to the bugcheck callbacks
    that the IFR data for this driver needs to be copied to the minidump file.
 
Arguments:
 
    DriverGlobals -
 
    BugCheckCode - Specifies a value that indicates the reason for the bug check.
 
    BugCheckParameter1 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter2 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter3 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter4 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
Return Value:
 
    None.

Routine Description:
 
    Common Driver Frameworks KeBugCheckEx() function. Cx should use this
    function rather than the system one or WdfVerifierKeBugCheck. This routine
    will indicate to the bugcheck callbacks that the IFR data for this driver or its
    client driver needs to be copied to the minidump file.
 
Arguments:
 
    DriverGlobals -
 
    Object - WDF uses this object to select which logs to write in the minidump.
        Cx can pass an object from the client driver's hierarchy to force
        the client driver's logs in the minidump.
 
    BugCheckCode - Specifies a value that indicates the reason for the bug check.
 
    BugCheckParameter1 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter2 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter3 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
    BugCheckParameter4 - Supply additional information, such as the address and
        data where a memory-corruption error occurred, depending on the value of
        BugCheckCode.
 
Return Value:
 
    None.
