示例1: openFile
RetCode ProcessFileSystem::openFile ( const std::string& path, bool, FileHandle& fh )
{
Entry* e = getEntry ( path );
if ( e == nullptr )
return NoSuchPath;
if ( e->file == nullptr )
return InvalidFileType;
assert ( e->file != nullptr );
assert ( e->dir == nullptr );
fh.Clear();
fh.set_hid ( HostId );
fh.set_fid ( genHandle ( e ) );
assert ( fh.fid() >= 0 );
RetCode rc = e->file->open ( fh );
if ( NotOk ( rc ) )
{
releaseHandle ( fh.fid() );
fh.Clear();
}
return rc;
}示例2: closeFile
RetCode ProcessFileSystem::closeFile ( const FileHandle& fh )
{
if ( fh.hid() != HostId )
return InvalidFileHandle;
Entry* e = handles_[fh.fid()];
if ( e == nullptr )
return InvalidFileHandle;
assert ( e->file != nullptr );
assert ( e->dir == nullptr );
e->file->close ( fh );
// we release the file handle regardless of errors (can't really be any)
releaseHandle ( fh.fid() );
return Success;
}示例3: readFile
RetCode ProcessFileSystem::readFile ( const FileHandle& fh, std::vector<char>& data,
off_t offset, size_t& processed ) const
{
Entry* e = handles_.at ( fh.fid() );
if ( e == nullptr || e->file == nullptr )
return InvalidFileHandle;
assert ( e->dir == nullptr );
return e->file->read ( fh, data, offset, processed );
