Read and write from temp file in Roku

问题:

In Roku, how do I read and write data from a temporary file in the folder tmp:? I cannot find any documentation relating to this. The data which I am storing is too big to be stored in the registry.

回答1:

There is two simple functions do read and write data from tmp:/ folder:

• ReadAsciiFile(filepath as String) as String

  text=ReadAsciiFile("tmp:/config.txt")

• WriteAsciiFile(filepath as String, text as String) as Boolean

  WriteAsciiFile("tmp:/config.txt", "the text to write")

Further documentation in source.
