# std::fsetpos

From cppreference.com
< cpp‎ | io‎ | c

Defined in header `<cstdio>` |  |
int fsetpos( std::FILE* stream, const std::fpos_t* pos ); |  |

Sets the file position indicator and the multibyte parsing state (if any) for the C file stream `stream` according to the value pointed to by `pos`.

Besides establishing new parse state and position, a call to this function undoes the effects of std::ungetc and clears the end-of-file state, if it is set.

If a read or write error occurs, the error indicator (std::ferror)for the stream is set.

### [edit] Parameters

stream | - | file stream to modify
pos | - | pointer to a fpos_t object obtained from std::fgetpos called on a stream associated with the same file

### [edit] Return value

​0​ upon success, nonzero value otherwise. Also, sets errno on failure.
