CCS/TMS320F28379D: Error-Highlight, when using funktion with default parameters

Marcel Kummer
Expert 1015 points

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hello everyone,

I just noticed, that when I use functions with default parameters like:

uint16_t* setupNewPacketHeader(uint32_t cmd, uint32_t length = empty, uint32_t state = RCX_S_OK);

The following line compiles correct, but is marked as error by the syntax-highlithing.

someVariable = *(setupNewPacketHeader(10));

Is this a bug or why is it highlighted?
CCS Version 8.3

    Hello Marcel,
    in 1-st case setupNewPacketHeader() has 2 params,
    in 2-nd only one.
    Any compiler warnings related to your 2-nd example?

    Hello,

    in 1-st case there are 3 params, 2 of those have a default value (because empty and RCX_S_OK are defines for 0)
    now I can call this function by giving 1, 2 or 3 parameters (c++ default values will fill the missing ones)
    (see en.cppreference.com/.../default_arguments)
    1) setupNewPacketHeader(10), same as setupNewPacketHeader(10, 0, 0)
    2) setupNewPacketHeader(10, 50), same as setupNewPacketHeader(10, 50, 0)
    3) setupNewPacketHeader(10,50,100)

    The compiler is perfectly fine if I only give 1 or 2 parameters when calling the function.
    But the syntax-highlighting thinks this function with only 1 parameter doesn't exist.

    Yes,
    3 not 2, typing error.
    Looks like the syntax highlighter syntax rules are not derived from the compiler and C/C++ standard used within a project.
    Probably Eclipse forum is better place to find how syntax highlighter works.

    If the compiler is not reporting an error but syntax errors are reported in the editor, then it may be coming from the Eclipse code analysis tools. Please take a look at the Code Analysis and Indexer sections of this article for more details and steps to get rid of these types of errors.
