CCS/TMS320F28388D: Where I can get the description of the macros define in the error code file; errno.h? How to test errno.c?

Part Number: TMS320F28388D


Tool/software: Code Composer Studio

Hi,

I am not able to find the description in the following code file, errno.h, which is located in the following pat:; C:\ti\ccs920\ccs\tools\compiler\ti-cgt-c2000_18.1.3.LTS\lib\src\errno.h

Could you guys please check and tell me where to find? is there any document provided?

Also, how test these macros, is there any use case?

Regards

Gurusha

    TI does not provide documentation for parts of C and C++ which are standard.  For details, please search the C28x compiler manual for the sub-chapter titled Related Documentation.

    Unfortunately, TI has published nothing on this topic.

    Thanks and regards,

    George,

    Since the header file contains so many macros but didn't mention the description of many of them, then how do we supposedly check on this part?

    Use the same web sites, training courses, tutorials, books etc. you use to learn C.  

    Another method to consider ... The function strerror returns a string that corresponds to an error code from errno.h.  The source code to all of the RTS, including strerror, is in a directory with a path similar to ...

    C:\ti\ccs1011\ccs\tools\compiler\ti-cgt-c2000_18.1.3.LTS\lib\src

    Here are the key lines in strerror.c ...

    _CODE_ACCESS char *strerror(int errnum)
{
   switch(errnum)
   {
      case 0      :  return ("No error");
      case EDOM   :  return ("Domain error");
      case ERANGE :  return ("Range error");
      case ENOENT :  return ("No such file or directory");
      case EFPOS  :  return ("File positioning error");
   }

   return ("Unknown error");
}

    Thanks and regards,
