10 .TH FSETPOS 3C "Jul 24, 2002"
12 fsetpos \- reposition a file pointer in a stream
18 \fBint\fR \fBfsetpos\fR(\fBFILE *\fR\fIstream\fR, \fBconst fpos_t *\fR\fIpos\fR);
24 The \fBfsetpos()\fR function sets the file position indicator for the stream
25 pointed to by \fIstream\fR according to the value of the object pointed to by
26 \fIpos\fR, which must be a value obtained from an earlier call to
27 \fBfgetpos\fR(3C) on the same stream.
30 A successful call to \fBfsetpos()\fR function clears the end-of-file indicator
31 for the stream and undoes any effects of \fBungetc\fR(3C) on the same stream.
32 After an \fBfsetpos()\fR call, the next operation on an update stream may be
33 either input or output.
37 The \fBfsetpos()\fR function returns \fB0\fR if it succeeds; otherwise it
38 returns a non-zero value and sets \fBerrno\fR to indicate the error.
42 The \fBfsetpos()\fR function may fail if:
49 The file descriptor underlying \fIstream\fR is not valid.
58 The file descriptor underlying \fIstream\fR is associated with a pipe, a FIFO,
65 The \fBfsetpos()\fR function has a transitional interface for 64-bit file
66 offsets. See \fBlf64\fR(5).
