The new position, measured 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. * * Returned Value: * Zero on success; -1 on failure with errno set appropriately. * ****************************************************************************/ int fseek(FAR FILE *stream, long int offset, int whence) { return fseeko(stream, offset, whence); }
