Member Typedef Documentation

typedef unsigned int ios_base::fmtflags

inherited

type for format flags

typedef unsigned char ios_base::iostate

inherited

typedef for iostate bitmask

typedef int32_t ios_base::off_type

inherited

type for relative seek offset

typedef uint8_t ios_base::openmode

inherited

typedef for iostream open mode

typedef uint32_t ios_base::pos_type

inherited

type for absolute seek position

typedef uint32_t ios_base::streamsize

inherited

unsigned size that can represent maximum file size. (violates spec - should be signed)

Member Enumeration Documentation

enum ios_base::seekdir

inherited

enumerated type for the direction of relative seeks

Enumerator
beg	seek relative to the beginning of the stream
cur	seek relative to the current stream position
end	seek relative to the end of the stream

Member Function Documentation

bool ios::bad ( ) const

inlineinherited

Returns: true if bad bit is set else false.

void ios::clear ( iostate state = goodbit )

inlineinherited

Clear iostate bits.

Parameters

[in] state The flags you want to set after clearing all flags.

bool ios::eof ( ) const

inlineinherited

Returns: true if end of file has been reached else false.

Warning: An empty file returns false before the first read.

Moral: eof() is only useful in combination with fail(), to find out whether EOF was the cause for failure

bool ios::fail ( ) const

inlineinherited

Returns: true if any iostate bit other than eof are set else false.

char ios_base::fill ( )

inlineinherited

Returns: fill character

char ios_base::fill ( char c )

inlineinherited

Set fill character

Parameters

[in] c new fill character

Returns: old fill character

fmtflags ios_base::flags ( ) const

inlineinherited

Returns: format flags

fmtflags ios_base::flags ( fmtflags fl )

inlineinherited

set format flags

Parameters

[in] fl new flag

Returns: old flags

bool ios::good ( ) const

inlineinherited

Returns: True if no iostate flags are set else false.

ios::operator const void * ( ) const

inlineinherited

Returns: null pointer if fail() is true.

bool ios::operator! ( ) const

inlineinherited

Returns: true if fail() else false.

int ios_base::precision ( ) const

inlineinherited

Returns: precision

int ios_base::precision ( unsigned int n )

inlineinherited

set precision

Parameters

[in] n new precision

Returns: old precision

iostate ios::rdstate ( ) const

inlineinherited

Returns: The iostate flags for this file.

fmtflags ios_base::setf ( fmtflags fl )

inlineinherited

set format flags

Parameters

[in] fl new flags to be or'ed in

Returns: old flags

fmtflags ios_base::setf	(	fmtflags	fl,
		fmtflags	mask
	)

inlineinherited

modify format flags

Parameters

[in]	mask	flags to be removed
[in]	fl	flags to be set after mask bits have been cleared

Returns: old flags

void ios::setstate ( iostate state )

inlineinherited

Set iostate bits.

Parameters

[in] state Bitts to set.

void ios_base::unsetf ( fmtflags fl )

inlineinherited

clear format flags

Parameters

[in] fl flags to be cleared

Returns: old flags

unsigned ios_base::width ( )

inlineinherited

Returns: width

unsigned ios_base::width ( unsigned n )

inlineinherited

set width

Parameters

[in] n new width

Returns: old width
