Module std.stdio

Standard I/O functions that extend core.stdc.stdio. core.stdc.stdio is publically imported when importing std.stdio.

Functions

Name	Description
chunks	Iterates through a file a chunk at a time by using foreach.
openNetwork	Experimental network access via the File interface
popen	Convenience function that forwards to core.sys.posix.stdio.popen with appropriately-constructed C-style strings.
readf	Read data from stdin according to the specified format specifier using std.format.formattedRead.
readln	Read line from stdin.
readln	Read line from stdin and write it to buf[], including terminating character.
write	For each argument arg in args, format the argument (as per to!(string)(arg)) and write the resulting string to args[0]. A call without any arguments will fail to compile.
writef	Writes formatted data to standard output (without a trailing newline).
writefln	Equivalent to writef(args, '\n').
writeln	Equivalent to write(args, '\n'). Calling writeln without arguments is valid and just prints a newline to the standard output.

Classes

Name	Description
StdioException	Thrown if I/O errors happen.

Structs

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

Enums

Name	Description
LockType	Used to specify the lock type for File.lock and File.tryLock.

Enum values

Name	Type	Description
isFileHandle		Indicates whether T is a file handle of some kind.

Global variables

Name	Type	Description
stderr	File	The standard error stream.
stdin	File	The standard input stream.
stdout	File	The standard output stream.

Aliases

Name	Type	Description
isStreamingDevice		Deprecated. Please use isFileHandle instead. This alias will be removed in June 2015.
KeepTerminator	Flag!("keepTerminator")	If flag KeepTerminator is set to KeepTerminator.yes, then the delimiter is included in the strings returned.
