[edit] Parameters
| stream | - | file stream to modify |
| offset | - | number of characters to shift the position relative to origin |
| origin | - | position to which offset is added. It can have one of the following values: SEEK_SET, SEEK_CUR, SEEK_END
|
[edit] Return value
0 upon success, nonzero value otherwise. Associated EOF flag is cleared for the stream and the effect of any ungetc is undone.
[edit] Notes
For text streams, the only valid values of offset are 0 (applicable to any origin) and a value returned by an earlier call to ftell (only applicable to SEEK_SET).
