mknod64(1) - a 64-bit version of mknod(1) Written by Robert Love This is mknod64(1), a version of mknod(1) that uses the 64-bit dev_t with a 32:32 split as implemented in later 2.5 kernels and set via mknod64(2). It is based on mknod(1) by David MacKenzie found in the GNU coreutils 5.0. It is a complete replacement for the original mknod, except it currently lacks support for specifying an initial mode (i.e., the --mode option). There is actually no reason to have both a mknod and a mknod64. The later will suffice for all purposes and thus should just be a future version of mknod. Until then, we have this separate package. REQUIREMENTS ============ Kernel 2.5.67-mm4 or later (yah, not even in Linus's 2.5 tree yet!) Obviously glibc does not yet support this. When it does, you may uncomment the DONT_NEED_MKNOD64_SETUP line in the Makefile. INSTALL ======= To build and install: $ make clean $ make $ su % make install Alternatively, you can create an RPM package from the tarball: $ rpmbuild -ta And install that: % rpm -Uvh USAGE ===== See 'man 1 mknod64' or 'mknod64 --help' mknod64(1) is the same as mknod(1) except (a) mode support is not yet added and (b) the major and minor may each be a 32-bit value. SYSCALL ======= The new mknod64() system call is defined as: long mknod64(const char *filename, int mode, unsigned int devhi, unsigned int devlo) Later 2.5 kernels support a 64-bit dev_t which is split 32:32 -- 32-bits for the major number and 32-bits for the minor number, as represented by 'devhi' and 'devlo', respectively. This mknod64(1) program allows you to specify a 32-bit value and uses the mknod64(2) system call.
