- s
- String
A managed string to be copied.
Returns
nativeint
The allocated memory block, or 0 if s is null.
- Attributes
Exceptions
There is insufficient memory available.
The length for s is out of range.
Remarks
StringToCoTaskMemAuto is useful for custom marshaling or for use when mixing managed and unmanaged code. Because this method allocates the unmanaged memory required for a string, always free the memory by calling FreeCoTaskMem. This method provides the opposite functionality of Marshal.PtrToStringAuto.
The characters of the string are copied as Unicode characters.
