class WriteAt
Defined at line 2141 of file fidling/gen/sdk/fidl/fuchsia.io/fuchsia.io/cpp/fidl/fuchsia.io/cpp/markers.h
Writes data at the provided offset.
Does not affect the seek offset.
The file size may grow if `offset` plus `data.length` is past the
current end of file.
+ request `data` the byte buffer to write to the file.
+ request `offset` the offset from start of the file to begin writing.
- response `actual_count` the number of bytes written.
## Invariants
* The returned `actual_count` will never be greater than `data.length`.
* If the server is unable to write all the data due to e.g. not enough
space, `actual_count` may be less than `data.length`. If no bytes
could be written, an error is returned.
* If `data.length` is zero, the server should perform all the checks
ensuring write access without mutating the file, and will return a
successful write of zero bytes.
This method requires the [`Rights.WRITE_BYTES`] right.
