Detailed Description

Base class for all streams.

Member Typedef Documentation

typedef unsigned int ios_base::fmtflags

type for format flags

typedef unsigned char ios_base::iostate

typedef for iostate bitmask

typedef int32_t ios_base::off_type

type for relative seek offset

typedef uint8_t ios_base::openmode

typedef for iostream open mode

typedef uint32_t ios_base::pos_type

type for absolute seek position

typedef uint32_t ios_base::streamsize

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

Member Enumeration Documentation

enum ios_base::seekdir

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
