SysAllocStringLen
pch, cch)
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.
