Routine Description:
|
||
|
|
||
|
Converts a unicode string to an ansi string. It is assumed
|
||
|
that the unicode string contains only ANSI characters (IP addresses,
|
||
|
port numbers, DNS names, etc) and that the out buffer is large enough
|
||
|
to hold the result.
|
||
|
|
||
|
Arguments:
|
||
|
|
||
|
in - Unicode string containing only ANSI characters.
|
||
|
If any of the high bytes are used they will be lost.
|
||
|
out - Buffer to put the result, assumed to be wcslen(in) + 1 bytes.
|
||
|
|
||
|
Return Value:
|
||
|
|
||
|
None
