Passing chars to WinAPI WinApi characters can have ANSI or Unicode values, while PowerBuilder characters have only Unicode values. ANSI Char values passed to and from WinAPI calls are automatically converted by PowerBuilder. Therefore, when defining character array length, you must always use the PowerBuilder character length (two bytes per character).
Passing chars to C functions Char variables passed to external C functions are converted to the C char type before passing. Arrays of Char variables are converted to the equivalent C array of char variables.
An array of Char variables embedded in a structure produces an embedded array in the C structure. This is different from an embedded String, which results in an embedded pointer to a string in the C structure.
