A note from Andries Brouwer, July 2007 #. > Is the story not rather more complicated for some calls like #. > stat(2)? #. Yes and no, mostly no. See /usr/include/sys/stat.h . #. The idea is here not so much that syscalls change, but that #. the definitions of struct stat and of the types dev_t and mode_t change. #. This means that libc (even if it does not call the kernel #. but only calls some internal function) must know what the #. format of dev_t or of struct stat is. #. The communication between the application and libc goes via #. the include file that defines a _STAT_VER and #. _MKNOD_VER describing the layout of the data that user space #. uses. Each (almost each) occurrence of stat() is replaced by #. an occurrence of xstat() where the first parameter of xstat() #. is this version number _STAT_VER. #. Now, also the definitions used by the kernel change. #. But glibc copes with this in the standard way, and the #. struct stat as returned by the kernel is repacked into #. the struct stat as expected by the application. #. Thus, _STAT_VER and this setup cater for the application-libc #. interface, rather than the libc-kernel interface. #.
