(_IO_file_close_mmap): New function. (_IO_file_jumps_mmap): New variable. * libio/wfileops.c (_IO_wfile_underflow): Reset read pointer before trying to convert rest of byte buffer. (_IO_wfile_underflow_mmap): New function. (_IO_wfile_jumps_mmap): New variable. * libio/iofopen.c (__fopen_maybe_mmap): New function. (__fopen_internal): New function. Split out from _IO_new_fopen. (_IO_new_fopen): Call __fopen_internal. * libio/iofopen64.c: Just call __fopen_internal. * libio/iofdopen.c: Call __fopen_maybe_mmap before returning successfully. * libio/iolibio.h: Declare __fopen_internal and __fopen_maybe_mmap. * libio/libioP.h: Declare _IO_file_jumps_mmap, _IO_wfile_jumps_mmap, _IO_file_close_mmap. * sysdeps/gnu/_G_config.h: Define _G_MMAP64. * sysdeps/unix/sysv/linux/cris/_G_config.h: Likewise. * stdio-common/Makefile (tests): Add tst-rndseek. * stdio-common/tst-rndseek.c: New file. --- libio/libioP.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'libio/libioP.h') diff --git a/libio/libioP.h b/libio/libioP.h index 3a32caa8b6..f9f44cc0d3 100644 --- a/libio/libioP.h +++ b/libio/libioP.h @@ -414,7 +414,9 @@ extern int _IO_default_showmanyc __P ((_IO_FILE *)); extern void _IO_default_imbue __P ((_IO_FILE *, void *)); extern struct _IO_jump_t _IO_file_jumps; +extern struct _IO_jump_t _IO_file_jumps_mmap; extern struct _IO_jump_t _IO_wfile_jumps; +extern struct _IO_jump_t _IO_wfile_jumps_mmap; extern struct _IO_jump_t _IO_old_file_jumps; extern struct _IO_jump_t _IO_streambuf_jumps; extern struct _IO_jump_t _IO_proc_jumps; @@ -488,6 +490,7 @@ extern _IO_size_t _IO_file_xsputn __P ((_IO_FILE *, const void *, _IO_size_t)); extern _IO_size_t _IO_file_xsgetn __P ((_IO_FILE *, void *, _IO_size_t)); extern int _IO_file_stat __P ((_IO_FILE *, void *)); extern int _IO_file_close __P ((_IO_FILE *)); +extern int _IO_file_close_mmap __P ((_IO_FILE *)); extern int _IO_file_underflow __P ((_IO_FILE *)); extern int _IO_file_overflow __P ((_IO_FILE *, int)); #define _IO_file_is_open(__fp) ((__fp)->_fileno != -1) -- cgit v1.2.3
