Porting a C array declaration to Delphi

I’m converting a C code to Delphi, and I want to convert a variable declaration, but I really don’t know.. Can you help?

char szImageName[BUFMAXLEN];

Thank you.

Answer 1

The Delphi equivalent is:

var
  szImageName: array [0..BUFMAXLEN-1] of AnsiChar;

Take care to use AnsiChar rather than Char since in modern versions of Delphi the generic type Char is aliased to the 2 byte WideChar. Of course if you are on pre-Unicode Delphi then this warning is not pertinent.

The biggest difference in the syntax is that all arrays in C have 0 as the lower bound. In Delphi you can specify whatever lower-bound you wish. Naturally to match the C code we specify 0 as our lower-bound.
