+;;; Large file support for Solaris. Define some of the 64-bit types +;;; we need. Unlike unix-glibc's large file support, Solaris's +;;; version is a little simpler because all of the 64-bit versions of +;;; the functions actually exist as functions. So instead of calling +;;; the 32-bit versions of the functions, we call the 64-bit versions. +;;; +;;; These functions are: creat64, open64, truncate64, ftruncate64, +;;; stat64, lstat64, fstat64, readdir64. +;;; +;;; There are also some new structures for large file support: +;;; dirent64, stat64. +;;; +;;; FIXME: We should abstract this better, but I (rtoy) don't have any +;;; other system to test this out on, so it's a Solaris hack for now. +#+solaris +(progn + (deftype file-offset64 () '(signed-byte 64)) + (def-alien-type off64-t int64-t) + (def-alien-type ino64-t u-int64-t) + (def-alien-type blkcnt64-t u-int64-t)) + ;;; The 64-bit version of struct dirent. #+solaris (def-alien-type nil @@ -1140,6 +1161,61 @@ (st-lspare long) (st-qspare (array long 4))))
