Defined in header <stdio.h>
typedef /* implementation-defined */ fpos_t;

fpos_t is a non-array complete object type, can be used to store (by fgetpos) and restore (by fsetpos) the position and multibyte parser state (if any) for a C stream.

The multibyte parser state of a wide-oriented C stream is represented by a mbstate_t object, whose value is stored as part of the value of a fpos_t object by fgetpos.

(since C95)
