Probably because it's guaranteed not to fail because of I/O errors: ERRORS EBADF fd is not an open file descriptor. EINVAL whence is not one of SEEK_SET, SEEK_CUR, SEEK_END; or the resulting file offset would be negative, or beyond the end of a seekable device. EOVERFLOW The resulting file offset cannot be represented in an off_t. ESPIPE fd is associated with a pipe, socket, or FIFO.
