|
|
* fsetpos - set the file position indicator for a stream (ANSI)
|
|
*
|
|
* This routine sets the file position indicator for a specified stream <iop>
|
|
* according to the value of the object pointed to by <pos>, which is a value
|
|
* obtained from an earlier call to fgetpos() on the same stream.
|
|
*
|
|
* A successful call to fsetpos() clears the end-of-file indicator for the
|
|
* stream and undoes any effects of ungetc() on the same stream. After an
|
|
* fsetpos() call, the next operation on an update stream may be either input
|
|
* or output.
|
|
*
|
|
* INCLUDE FILES: stdio.h
|
|
*
|
|
* RETURNS:
|
|
* Zero, or non-zero if the call fails, with `errno' set to indicate the error.
