fpos 클래스

아티클
06/09/2015

The template class describes an object that can store all the information needed to restore an arbitrary file-position indicator within any stream. An object of class fpos<St> effectively stores at least two member objects:

A byte offset, of type streamoff.
A conversion state, for use by an object of class basic_filebuf, of type St, typically mbstate_t.

It can also store an arbitrary file position, for use by an object of class basic_filebuf, of type fpos_t. For an environment with limited file size, however, streamoff and fpos_t may sometimes be used interchangeably. For an environment with no streams that have a state-dependent encoding, mbstate_t may actually be unused. Therefore, the number of member objects stored may vary.

연산자

operator!=	Tests file-position indicators for inequality.
operator+	Increments a file-position indicator.
연산자+=	Increments a file-position indicator.
operator-	Decrements a file-position indicator.
operator-=	Decrements a file-position indicator.
operator==	Tests file-position indicators for equality.
operator streamoff	Casts object of type fpos to object of type streamoff.
