| Name | Description |
|---|---|
| WriteAsync(ByteBuffer[]) |
Runs a synchronous gathering write from all supplied buffers in a task at the file position, or at the end of the file in append mode, advancing the file position by the number of bytes written. |
| WriteAsync(ByteBuffer) |
Runs a synchronous write in a task at this channel's file position, or at the end of the file in append mode, advancing the file position by the number of bytes written. |
| WriteAsync(ByteBuffer, Int64) |
Runs a synchronous write in a task at the specified file offset without changing this channel's current file position. |
| WriteAsync(ByteBuffer[], Int32, Int32) |
Runs a synchronous gathering write from the selected buffers in a task at the file position, or at the end of the file in append mode, advancing the file position by the number of bytes written. |
WriteAsync(ByteBuffer[])
Runs a synchronous gathering write from all supplied buffers in a task at the file position, or at the end of the file in append mode, advancing the file position by the number of bytes written.
public System.Threading.Tasks.Task<long> WriteAsync(Java.Nio.ByteBuffer[]? srcs);member this.WriteAsync : Java.Nio.ByteBuffer[] -> System.Threading.Tasks.Task<int64>Parameters
- srcs
- ByteBuffer[]
The source buffers in array order. Each buffer's position advances by the bytes taken from it; buffer limits are unchanged.
Returns
A task whose result is the total number of bytes written, possibly zero. The result gives the actual count of bytes written from the buffers.

Applies to
WriteAsync(ByteBuffer)
Runs a synchronous write in a task at this channel's file position, or at the end of the file in append mode, advancing the file position by the number of bytes written.
public System.Threading.Tasks.Task<int> WriteAsync(Java.Nio.ByteBuffer? src);member this.WriteAsync : Java.Nio.ByteBuffer -> System.Threading.Tasks.Task<int>Parameters
- src
- ByteBuffer
The source buffer. Its position advances by the number of bytes written; its limit is unchanged.
Returns
A task whose result is the number of bytes written, possibly zero. The result gives the actual count of bytes written from the buffer.

Applies to
WriteAsync(ByteBuffer, Int64)
Runs a synchronous write in a task at the specified file offset without changing this channel's current file position.
public System.Threading.Tasks.Task<int> WriteAsync(Java.Nio.ByteBuffer? src, long position);member this.WriteAsync : Java.Nio.ByteBuffer * int64 -> System.Threading.Tasks.Task<int>Parameters
- src
- ByteBuffer
The source buffer. Its position advances by the number of bytes written; its limit is unchanged.
- position
- Int64
The non-negative byte offset in the file at which to start writing. The file grows if needed; bytes in any gap before the written data have unspecified values.
Returns
A task whose result is the number of bytes written, possibly zero. The result gives the actual count of bytes written from the buffer.

Applies to
WriteAsync(ByteBuffer[], Int32, Int32)
Runs a synchronous gathering write from the selected buffers in a task at the file position, or at the end of the file in append mode, advancing the file position by the number of bytes written.
public System.Threading.Tasks.Task<long> WriteAsync(Java.Nio.ByteBuffer[]? srcs, int offset, int length);member this.WriteAsync : Java.Nio.ByteBuffer[] * int * int -> System.Threading.Tasks.Task<int64>Parameters
- srcs
- ByteBuffer[]
The source buffer array. Selected buffers are read in array order, advancing their positions without changing their limits.
- offset
- Int32
The index of the first source buffer, from zero through the array length.
- length
- Int32
The number of source buffers to use, from zero through the array length minus offset.
Returns
A task whose result is the total number of bytes written, possibly zero. The result gives the actual count of bytes written from the selected buffers.
