    (const str : pnstr; 
     position : pnstr 
  ) : pnstr;

Parameters

string
(IN) Points to the beginning of the string.
position
(IN) Points to a character in the NULL-terminated string.

Return Values

0x0000

The string parameter is NULL

non-zero

Pointer to the previous character in the string. If the position parameter is equal to the string parameter, this value points to the first character in the string

Remarks

In a multibyte string, it is not obvious whether the current byte is a single-byte character or the second character of a double-byte character. NWPrevChar resolves this ambiguity.
