/***

*wchar_t *_wcsdup(string) - duplicate string into malloc'd memory
|
|
*
|
|
*Purpose:
|
|
* Allocates enough storage via malloc() for a copy of the
|
|
* string, copies the string into the new memory, and returns
|
|
* a pointer to it (wide-character).
|
|
*
|
|
*Entry:
|
|
* wchar_t *string - string to copy into new memory
|
|
*
|
|
*Exit:
|
|
* returns a pointer to the newly allocated storage with the
|
|
* string in it.
|
|
*
|
|
* returns NULL if enough memory could not be allocated, or
|
|
* string was NULL.
