Input-Output base classes

Header providing base classes and types for the IOStream hierarchy of classes:

Types

Class templates

basic_ios

Base class for streams (type-dependent components) (class template )

fpos

Stream position class template (class template )

Classes

ios

Base class for streams (type-dependent components) (class )

ios_base

Base class for streams (class )

wios

Base class for wide character streams (class )

Other types

io_errc

Input/output error conditions (enum class )

streamoff

Stream offset type (type )

streampos

Stream position type (type )

streamsize

Stream size type (type )

wstreampos

Wide stream position type (type )

Format flag manipulators (functions)

Independent flags (switch on):

boolalpha

Alphanumerical bool values (function )

showbase

Show numerical base prefixes (function )

showpoint

Show decimal point (function )

showpos

Show positive signs (function )

skipws

Skip whitespaces (function )

unitbuf

Flush buffer after insertions (function )

uppercase

Generate upper-case letters (function )

Independent flags (switch off):

noboolalpha

No alphanumerical bool values (function )

noshowbase

Do not show numerical base prefixes (function )

noshowpoint

Do not show decimal point (function )

noshowpos

Do not show positive signs (function )

noskipws

Do not skip whitespaces (function )

nounitbuf

Do not force flushes after insertions (function )

nouppercase

Do not generate upper case letters (function )

Numerical base format flags ("basefield" flags):

dec

Use decimal base (function )

hex

Use hexadecimal base (function )

oct

Use octal base (function )

Floating-point format flags ("floatfield" flags):

fixed

Use fixed floating-point notation (function )

scientific

Use scientific floating-point notation (function )

Adustment format flags ("adjustfield" flags):

internal

Adjust field by inserting characters at an internal position (function )

left

Adjust output to the left (function )

right

Adjust output to the right (function )

Other functions

iostream_category 

Return iostream category (function )

Notice that not all standard manipulators are defined in this header. Input streams also support ws, and output streams endl, ends and flush. Streams also support an additional set of manipulators, which are parametric and defined apart in header <iomanip>. These are: setiosflags, resetiosflags, setbase, setfill, setprecision, setw
