OLECHAR FAR* pch
unsigned int cch Allocates a new string, copies cch characters from the passed string into it, and then appends a null character. Parameter pch A pointer to cch characters to copy, or NULL to keep the string uninitialized. cch Number of characters to copy from pch*. A null character is placed afterwards, making a total of cch+1 characters allocated. Return Value Points to a copy of the string or NULL, if insufficient memory exists. Comments If pch is NULL, a string of the requested length is allocated, but not initialized. The string pch can contain embedded null characters and need not end with a null. The returned string should later be freed with SysFreeString.
