(_IO_file_jumps_mmap): Use it. (_IO_file_underflow_mmap): Rewritten. If after EOF or fflush, repeat the stat check and resize the mapped buffer as necessary. 2002-07-31 Roland McGrath <roland@frob.com> * libio/fileops.c (decide_maybe_mmap): New static function. Code taken from libio/iofopen.c:__fopen_maybe_mmap to try to mmap the file contents. Then switch the jump tables to the mmap tables if it worked, or the vanilla file tables if not. (_IO_file_underflow_maybe_mmap): New function. (_IO_file_seekoff_maybe_mmap): New function. (_IO_file_xsgetn_maybe_mmap): New function. (_IO_file_jumps_maybe_mmap): New variable, jump table using those. * libio/libioP.h: Declare those. * libio/wfileops.c (_IO_wfile_underflow_maybe_mmap): New function. (_IO_wfile_jumps_maybe_mmap): New variable, jump table using that. * libio/iofopen.c (__fopen_maybe_mmap): Don't try to mmap here. If the stream is read-only, set its jump tables to those new ones. * libio/iofdopen.c (_IO_new_fdopen) [_G_HAVE_MMAP]: Set the initial jump tables to the maybe_mmap ones, and don't call __fopen_maybe_mmap. We need the tables set before _IO_file_attach. * libio/tst-mmap-eofsync.c: New file. * libio/tst-mmap-fflushsync.c: New file. * libio/bug-mmap-fflush.c: New file. * libio/tst-mmap2-eofsync.c: New file. * libio/Makefile (tests): Add them. * libio/wfileops.c (_IO_wfile_underflow_mmap): Don't set EOF bit when _IO_file_underflow_mmap fails, it already set the appropriate bit.
