Detailed Description
The base of the I/O class hierarchy.
This class defines everything that can be defined about I/O that does
not depend on the type of characters being input or output. Most people
will only see ios_base when they need to specify the full name of the
various I/O flags (e.g., the openmodes).

Member Typedef Documentation
typedef void(* std::ios_base::event_callback)(event __e, ios_base &__b, int
__i)
The type of an event callback function.
Parameters:
__e One of the members of the event enum.
__b Reference to the ios_base object.
__i The integer provided when the callback was registered.
Event callbacks are user defined functions that get called during
several ios_base and basic_ios functions, specifically imbue(),
copyfmt(), and ~ios().
Definition at line 436 of file ios_base.h.

· hex
· internal
· left
· oct
· right
· scientific
· showbase
· showpoint

Right Thing to happen. Defined objects of type iostate are:
· badbit
· eofbit
· failbit
· goodbit
Definition at line 330 of file ios_base.h.

· end, equivalent to SEEK_END in the C standard library.
Definition at line 393 of file ios_base.h.
Member Enumeration Documentation
enum std::ios_base::event
The set of events that may be passed to an event callback. erase_event
is used during ~ios() and copyfmt(). imbue_event is used during
imbue(). copyfmt_event is used during copyfmt().
Definition at line 419 of file ios_base.h.
Constructor & Destructor Documentation
virtual std::ios_base::~ios_base () [virtual]
Invokes each callback with erase_event. Destroys local storage.
Note that the ios_base object for the standard streams never gets
destroyed. As a result, any callbacks registered with the standard
streams will not get invoked with erase_event (unless copyfmt is used).
Member Function Documentation
const locale& std::ios_base::_M_getloc () const [inline]
Locale access.
Returns:
A reference to the current locale.
Like getloc above, but returns a reference instead of generating a
copy.

fmtflags std::ios_base::flags () const [inline]
Access to format flags.
Returns:
The format control flags for both input and output.

>::operator<<(), std::operator<<(), std::operator>>(), and
std::basic_istream< _CharT, _Traits >::sentry::sentry().
fmtflags std::ios_base::flags (fmtflags__fmtfl) [inline]
Setting new format flags all at once.
Parameters:
__fmtfl The new flags to set.
Returns:
The previous format control flags.
This function overwrites all the format flags with __fmtfl.
Definition at line 562 of file ios_base.h.
locale std::ios_base::getloc () const [inline]
Locale access.
Returns:
A copy of the current locale.
If imbue(loc) has previously been called, then this function returns
loc. Otherwise, it returns a copy of std::locale(), the global C++
locale.
Definition at line 695 of file ios_base.h.
Referenced by std::basic_ios< _CharT, _Traits >::copyfmt(),
std::money_put< _CharT, _OutIter >::do_put(), std::operator>>(), and

locale std::ios_base::imbue (const locale &__loc)
Setting a new locale.
Parameters:
__loc The new locale.
Returns:
The previous locale.
Sets the new locale for this stream, and then invokes each callback
with imbue_event.
Referenced by std::basic_ios< _CharT, _Traits >::imbue().
long& std::ios_base::iword (int__ix) [inline]
Access to integer array.
Parameters:
__ix Index into the array.
Returns:
A reference to an integer associated with the index.
The iword function provides access to an array of integers that can be
used for any purpose. The array grows as required to hold the supplied
index. All integers in the array are initialized to 0.
The implementation reserves several indices. You should use xalloc to
obtain an index that is safe to use. Also note that since the array can
grow dynamically, it is not safe to hold onto the reference.
Definition at line 741 of file ios_base.h.
streamsize std::ios_base::precision () const [inline]
Flags access.
Returns:
The precision to generate on certain output operations.
Be careful if you try to give a definition of precision here; see DR
189.
Definition at line 621 of file ios_base.h.
Referenced by std::basic_ios< _CharT, _Traits >::copyfmt(), and
std::operator<<().
streamsize std::ios_base::precision (streamsize__prec) [inline]
Changing flags.
Parameters:
__prec The new precision value.
Returns:
The previous value of precision().
Definition at line 630 of file ios_base.h.
void*& std::ios_base::pword (int__ix) [inline]
Access to void pointer array.
Parameters:
__ix Index into the array.
Returns:
A reference to a void* associated with the index.
The pword function provides access to an array of pointers that can be
used for any purpose. The array grows as required to hold the supplied
index. All pointers in the array are initialized to 0.
The implementation reserves several indices. You should use xalloc to
obtain an index that is safe to use. Also note that since the array can
grow dynamically, it is not safe to hold onto the reference.
Definition at line 762 of file ios_base.h.
void std::ios_base::register_callback (event_callback__fn, int__index)
Add the callback __fn with parameter __index.
Parameters:
__fn The function to add.
__index The integer to pass to the function when invoked.
Registers a function as an event callback with an integer parameter to
be passed to the function when invoked. Multiple copies of the function
are allowed. If there are multiple callbacks, they are invoked in the
order they were registered.
fmtflags std::ios_base::setf (fmtflags__fmtfl) [inline]
Setting new format flags.
Parameters:
__fmtfl Additional flags to set.
Returns:
The previous format control flags.
This function sets additional flags in format control. Flags that were
previously set remain set.
Definition at line 578 of file ios_base.h.
Referenced by std::dec(), std::fixed(), std::hex(), std::left(),
std::oct(), std::right(), std::scientific(), std::showbase(),
std::showpoint(), std::showpos(), std::skipws(), std::unitbuf(), and
std::uppercase().
fmtflags std::ios_base::setf (fmtflags__fmtfl, fmtflags__mask) [inline]
Setting new format flags.
Parameters:
__fmtfl Additional flags to set.
__mask The flags mask for fmtfl.
Returns:
The previous format control flags.
This function clears mask in the format flags, then sets fmtfl & mask.
An example mask is ios_base::adjustfield.
Definition at line 595 of file ios_base.h.
static bool std::ios_base::sync_with_stdio (bool__sync = true) [static]
Interaction with the standard C I/O objects.
Parameters:
__sync Whether to synchronize or not.
Returns:
True if the standard streams were previously synchronized.
The synchronization referred to is only that between the standard C
facilities (e.g., stdout) and the standard C++ objects (e.g., cout).
User-declared streams are unaffected. See
http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt11ch28s02.html
void std::ios_base::unsetf (fmtflags__mask) [inline]
Clearing format flags.
Parameters:
__mask The flags to unset.
This function clears __mask in the format flags.

std::noshowpoint(), std::noshowpos(), std::noskipws(),

streamsize std::ios_base::width () const [inline]
Flags access.
Returns:
The minimum field width to generate on output operations.
Minimum field width refers to the number of characters.
Definition at line 644 of file ios_base.h.
Referenced by std::basic_ios< _CharT, _Traits >::copyfmt(),
std::num_put< _CharT, _OutIter >::do_put(), and std::operator>>().
streamsize std::ios_base::width (streamsize__wide) [inline]
Changing flags.
Parameters:
__wide The new width value.
Returns:
The previous value of width().
Definition at line 653 of file ios_base.h.
static int std::ios_base::xalloc () [static]
Access to unique indices.
Returns:
An integer different from all previous calls.
This function returns a unique integer every time it is called. It can
be used for any purpose, but is primarily intended to be a unique index
for the iword and pword functions. The expectation is that an
application calls xalloc in order to obtain an index in the iword and
pword arrays that can be used without fear of conflict.
The implementation maintains a static variable that is incremented and
returned on each invocation. xalloc is guaranteed to return an index
that is safe to use in the iword and pword arrays.
