WCHAR argument pointer Resolved

[bkelly13]

The dot H file contains:

= L"C:\\LOG_FILES\\";

const WCHAR DEFAULT_FILENAME_PREFIX[] = L"Log_File_";

The dot CPP file contains

C_Log_Writer::C_Log_Writer(
const WCHAR *new_directory_name = &DEFAULT_DlRECTORY,
const WCHAR *new_name_prefix = &DEFAULT_FILENAME_PREFIX[0] )
{ ... }

The new_directory_name lines does not compile and produces the error:

Error 1 error C2440: 'default argument' : cannot convert from 'const WCHAR (*)[14]' to 'const WCHAR *' e:\code_tests\common_code_dll\c_log_writer\c_log_writer.cpp 73 1 C_Log_Writer

I thought new_directory_name would be a pointer that would by default point to the first character of the array. Why is that thinking wrong?

Because you're trying to assign a pointer-to-a-pointer to a pointer:

const WCHAR *new_directory_name = &DEFAULT_DlRECTORY

should be

const WCHAR *new_directory_name = DEFAULT_DlRECTORY

The difficult we do right away... ...the impossible takes slightly longer.

And that is because DEFAULT_DlRECTORY is an array and passing it as an argument means the address of the first character is passed. Ok, I must confess to being ate up with the dumb ass there. Thank you for taking the time for a gentle kick in the butt.
