Read(Byte[], Int64, UIntPtr, NSError)
Read data from a resource.
public UIntPtr Read(byte[] buffer, long offset, UIntPtr length, out Foundation.NSError? error);member this.Read : byte[] * int64 * unativeint * NSError -> unativeintParameters
- buffer
- Byte[]
An array of bytes where the read data will be stored.
- offset
- Int64
The zero-based byte offset in buffer at which to begin storing the data read from the current resource.
- length
-
UIntPtr
unativeint
The maximum number of bytes to be read from the current resource.
- error
- NSError
The error object if the operation fails, null otherwise.
Returns
unativeint
The number of bytes read.
