The new position, mea- + sured in bytes, is obtained by adding offset bytes to the + position specified by whence. If whence is set to + SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to + the start of the file, the current position indicator, or + end-of-file, respectively. A successful call to the fseek + function clears the end-of-file indicator for the stream + and undoes any effects of the ungetc(3) function on the + same stream. + + The ftell function obtains the current value of the file + position indicator for the stream pointed to by stream. + + The rewind function sets the file position indicator for + the stream pointed to by stream to the beginning of the + file. It is equivalent to: + + (void)fseek(stream, 0L, SEEK_SET) + + except that the error indicator for the stream is also + cleared (see clearerr(3). + + The fgetpos and fsetpos functions are alternate interfaces + equivalent to ftell and fseek (with whence set to + SEEK_SET), setting and storing the current value of the + file offset into or from the object referenced by pos. On + some non-UNIX systems an fpos_t object may be a complex + object and these routines may be the only way to portably + reposition a text stream. + +<h3>RETURN VALUES +</h3> The rewind function returns no value. Upon successful + completion, fgetpos, fseek, fsetpos return 0, and ftell + returns the current offset. Otherwise, -1 is returned and + the global variable errno is set to indicate the error. + +<h3>ERRORS +</h3> EBADF The stream specified is not a seekable stream. + + + + +<h3>BSD MANPAGE 29 November 1993 1 +</h3> + + + + +<h3>FSEEK(3) Linux Programmer's Manual FSEEK(3) +</h3> + + EINVAL The whence argument to fseek was not SEEK_SET, + SEEK_END, or SEEK_CUR. + + The function fgetpos, fseek, fsetpos, and ftell may also + fail and set errno for any of the errors specified for the + routines fflush(3), fstat(2), lseek(2), and malloc(3). + +</pre> +<hr> +<h3>SEE ALSO +</h3><p> +<a href=lseek.htm>lseek</a>, +<pre> + +<h3>STANDARDS +</h3> The fgetpos, fsetpos, fseek, ftell, and rewind functions + conform to ANSI C3.159-1989 (``ANSI C''). + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +<h3>BSD MANPAGE 29 November 1993 2 +</h3> + +
