Update.
2002-01-19 Ulrich Drepper <drepper@redhat.com>
* libio/fileops.c (_IO_file_underflow_mmap): Don't define as static.
Set offset if read end wasn't the buffer end.
(_IO_file_seekoff_mmap): New function.
(_IO_file_xsgetn_mmap): New function.
(_IO_file_jumps_mmap): Use the two new functions.
* libio/wfileops.c (_IO_wfile_underflow_mmap): Handle end read buffer
!= end buffer.
* libio/libioP.h: Declare _IO_file_seekoff_mmap and
_IO_file_underflow_mmap.
* libio/iofopen.c: Don't position file descriptor at end of file.
* libio/tst-widetext.c: Improve error messages.
* stdio-common/tst-rndseek.c: Likewise.
