参数

[in]	s	The StringView containing the characters to be written.
[out]	N/A
[in,out]	N/A

返回

ReadWriteAccessor & ReadWriteAccessor对象

注解

Writes the content of a StringView to the file.This operator is just a comfort feature for non-safety critical applications. If an error occurs during this operation, it is silently ignored.

SetFileSize()

ara::core::Result< void > ara::per::ReadWriteAccessor::SetFileSize ( std::uint64_t  size )

noexcept

Reduces the size of the file to ’size’, effectively removing the current content of the file beyond this size.

Function Implementation

模板参数

N/A

参数

[in]	size	New size of the file.
[out]	N/A
[in,out]	N/A

返回

ara::core::Result<void> A Result of void. In case of an error, it contains any of the errors defined below, or a vendor specific error.

注解

The current file position is unchanged if it is lower than ’size’, or set to the last valid position in the file otherwise. If ’size’ is 0, the current file position will also be set to 0.

返回

ara::core::Result<void> A Result of void. In case of an error, it contains any of the errors defined below, or a vendor specific error.

注解

The time when the content is persisted depends on the implementation of Persistency. SyncToFile can be used to force Persistency to persist the file content.
