Functions:
|
||||
|
||||
\begin{outline}
|
||||
\1\textbf{pread}(pointer: Int, count: Int, offset: Int)
|
||||
\\Reads the file bytewise and puts it to the memory starting from the \code{pointer}.
|
||||
\2\code{count}: how many bytes to read
|
||||
\2\code{offset}: when reading a file, how many bytes to skip initially
|
||||
\1\textbf{bread}(): Array
|
||||
\\Reads the file bytewise and returns the content in Javascript array.
|
||||
\1\textbf{sread}(): String
|
||||
\\Reads the file textwise and returns the content in Javascript string.
|
||||
\1\textbf{pwrite}(pointer: Int, count: Int, offset: Int)
|
||||
\\Writes the bytes stored in the memory starting from the \code{pointer} to file.
|
||||
\2\code{count}: how many bytes to write
|
||||
\2\code{offset}: when writing to the file, how many bytes on the file to skip before writing a first byte.
|
||||
\1\textbf{bwrite}(bytes: UintArray)
|
||||
\\Writes the bytes to the file.
|
||||
\1\textbf{swrite}(string: String)
|
||||
\\Writes the string to the file.
|
||||
\1\textbf{flush}()
|
||||
\\Flush the contents on the write buffer to the file immediately. Will do nothing if there is no write buffer implemented --- a write operation will always be performed imemdiately in such cases.
|
||||
\1\textbf{close}()
|
||||
\\Tells the underlying device (usually a disk drive) to close a file. When dealing with multiple files on a single disk drive (of which can only have a single active---or opened---file), the underlying filesystem driver will automatically swap the files around, so this function is normally unused.
|
||||
\1\textbf{list}(): Array or undefined
|
||||
\\Lists files inside of the directory. If the path is indeed a directory, an array of file descriptors will be returned; \code{undefined} otherwise.
|
||||
\1\textbf{touch}(): Boolean
|
||||
\\Updates the file's access time if the file exists; a new file will be created otherwise. Returns true if successful.
|
||||
\1\textbf{mkDir}(): Boolean
|
||||
\\Creates a directory to the path. Returns true if successful.
|
||||
\1\textbf{mkFile}(): Boolean
|
||||
\\Creates a new file to the path. Returns true if successful.
|
||||
\1\textbf{remove}(): Boolean
|
||||
\\Removes a file. Returns true if successful.
