• File

  Encapsulates a $(D FILE*). Generally D does not attempt to provide thin wrappers over equivalent functions in the C standard library, but manipulating $(D FILE*) values directly is unsafe and error-prone in many ways. The $(D File) type ensures safe manipulation, automatic file closing, and a lot of convenience.

• LockingTextReader

• isFileHandle(T)

  Indicates whether $(D T) is a file handle of some kind.

• isStreamingDevice

  $(RED Scheduled for deprecation in January 2013. Please use $(D isFileHandle) instead.)

• write(T...) if (!is(T[0] : File))

  For each argument $(D arg) in $(D args), format the argument (as per $(LINK2 std_conv.html, to!(string)(arg))) and write the resulting string to $(D args[0]). A call without any arguments will fail to compile.

• writeln(T...)

  Equivalent to $(D write(args, '\n')). Calling $(D writeln) without arguments is valid and just prints a newline to the standard output.

• writef(T...)

  If the first argument $(D args[0]) is a $(D FILE*), use $(LINK2 std_format.html#format-string, the format specifier) in $(D args[1]) to control the formatting of $(D args[2..$]), and write the resulting string to $(D args[0]). If $(D arg[0]) is not a $(D FILE*), the call is equivalent to $(D writef(stdout, args)).

• writefln(T...)

  Equivalent to $(D writef(args, '\n')).

• readf(A...)

  Read data from $(D stdin) according to the specified $(LINK2 std_format.html#format-string, format specifier) using $(XREF format,formattedRead).

• readln

  Read line from stream $(D fp). Returns: $(D null) for end of file, $(D char[]) for line read from $(D fp), including terminating character Params: $(D fp) = input stream $(D terminator) = line terminator, '\n' by default Throws: $(D StdioException) on error Example: Reads $(D stdin) and writes it to $(D stdout). --- import std.stdio;

• readln

  Read line from stream $(D fp). Returns: $(D null) for end of file, $(D char[]) for line read from $(D fp), including terminating character Params: $(D fp) = input stream $(D terminator) = line terminator, '\n' by default Throws: $(D StdioException) on error Example: Reads $(D stdin) and writes it to $(D stdout). --- import std.stdio;

• popen

• popen

  Convenience function that forwards to $(D std.c.stdio.popen) with appropriately-constructed C-style strings.

• binaryWrite(T)

• lines

  Iterates through the lines of a file by using $(D foreach).

• chunks

  Iterates through a file a chunk at a time by using $(D foreach).

• StdioException

  Thrown if I/O errors happen.

• std_stdio_static_this

• stdin

  The standard input stream.

• stdout

  The standard output stream.

• stderr

  The standard error stream.

• openNetwork

  Experimental network access via the File interface
