Purpose: This function converts a wide-char string to a multi-byte

string.
|
|
|
|
If pszBuf is non-NULL and the converted string can fit in
|
|
pszBuf, then *ppszAnsi will point to the given buffer.

Otherwise, this function will allocate a buffer that can
|
|
hold the converted string.
|
|
|
|
If pszWide is NULL, then *ppszAnsi will be freed. Note
|
|
that pszBuf must be the same pointer between the call
|
|
that converted the string and the call that frees the
|
|
string.
