- s
- String
A managed string to be copied.
Returns
nativeint
An integer representing a pointer to the block of memory allocated for the string, or 0 if s is null.
- Attributes
Exceptions
There is insufficient memory available.
The s parameter exceeds the maximum length allowed by the operating system.
Remarks
StringToCoTaskMemAnsi is useful for custom marshaling or 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.PtrToStringAnsi. The characters of the string are copied as ANSI characters.
