Struct sgx_tprotected_fs::SgxFile
source · [−]pub struct SgxFile { /* private fields */ }
Expand description
A reference to an open Sgxfile on the filesystem.
An instance of a SgxFile
can be read and/or written depending on what options
it was opened with. SgxFiles also implement [Seek
] to alter the logical cursor
that the file contains internally.
SgxFiles are automatically closed when they go out of scope.
