Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped. The main things grep needs to know about mmap are: * does it exist and is it safe to write into the mmap'd area * how to use it (BSD variants) */ #include #include #if !defined STDC_HEADERS && !defined HAVE_STDLIB_H char *malloc (); #endif /* This mess was copied from the GNU getpagesize.h. */ #ifndef HAVE_GETPAGESIZE # ifdef _SC_PAGESIZE # define getpagesize() sysconf(_SC_PAGESIZE) # else /* no _SC_PAGESIZE */ # ifdef HAVE_SYS_PARAM_H # include # ifdef EXEC_PAGESIZE # define getpagesize() EXEC_PAGESIZE # else /* no EXEC_PAGESIZE */ # ifdef NBPG # define getpagesize() NBPG * CLSIZE # ifndef CLSIZE # define CLSIZE 1 # endif /* no CLSIZE */ # else /* no NBPG */ # ifdef NBPC # define getpagesize() NBPC # else /* no NBPC */ # ifdef PAGESIZE # define getpagesize() PAGESIZE # endif /* PAGESIZE */ # endif /* no NBPC */ # endif /* no NBPG */ # endif /* no EXEC_PAGESIZE */ # else /* no HAVE_SYS_PARAM_H */ # define getpagesize() 8192 /* punt totally */ # endif /* no HAVE_SYS_PARAM_H */ # endif /* no _SC_PAGESIZE */ #endif /* no HAVE_GETPAGESIZE */ int main () { char *data, *data2, *data3; const char *cdata2; int i, pagesize; int fd, fd2; pagesize = getpagesize (); /* First, make a file with some known garbage in it. */ data = (char *) malloc (pagesize); if (!data) return 1; for (i = 0; i < pagesize; ++i) *(data + i) = rand (); umask (0); fd = creat ("conftest.mmap", 0600); if (fd < 0) return 2; if (write (fd, data, pagesize) != pagesize) return 3; close (fd); /* Next, check that the tail of a page is zero-filled.
