* Darwin: Fix compilation warning regarding the deprecated daemon() functionAlexandre Raymond2011-06-141-0/+16
| | | | | | | | | | | | | | | | | | | | | | Changes since v1: create a wrapper function named qemu_daemon() in oslib-posix.c instead of putting the OS specific workaround in qemu-nbd.c directly. On OSX >= 10.5, daemon() is deprecated, resulting in the following warning: ----8<---- qemu-nbd.c: In function ‘main’: qemu-nbd.c:371: warning: ‘daemon’ is deprecated (declared at /usr/include/stdlib.h:289) ----8<---- The following trick, used in mDNSResponder, takes care of this warning: http://www.opensource.apple.com/source/mDNSResponder/mDNSResponder-258.18/mDNSPosix/PosixDaemon.c On OSX, it temporarily renames the daemon() function before including stdlib.h and declares it manually as an extern function. This way, the compiler does not see the declaration from stdlib.h and thus does not display the warning.

* virtio-9p: fix build on !CONFIG_UTIMENSATHidetoshi Seto2010-12-021-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduce a fallback mechanism for old systems that do not support utimensat(). This fix build failure with following warnings: hw/virtio-9p-local.c: In function 'local_utimensat': hw/virtio-9p-local.c:479: warning: implicit declaration of function 'utimensat' hw/virtio-9p-local.c:479: warning: nested extern declaration of 'utimensat' and: hw/virtio-9p.c: In function 'v9fs_setattr_post_chmod': hw/virtio-9p.c:1410: error: 'UTIME_NOW' undeclared (first use in this function) hw/virtio-9p.c:1410: error: (Each undeclared identifier is reported only once hw/virtio-9p.c:1410: error: for each function it appears in.) hw/virtio-9p.c:1413: error: 'UTIME_OMIT' undeclared (first use in this function) hw/virtio-9p.c: In function 'v9fs_wstat_post_chmod': hw/virtio-9p.c:2905: error: 'UTIME_OMIT' undeclared (first use in this function) [NOTE: At this time virtio-9p is only user of utimensat(), and is available only when host is linux and CONFIG_VIRTFS is defined. So there are no similar warning for win32. Please provide a wrapper for win32 in oslib-win32.c if new user really requires it.] v5: - Allow fallback on runtime - Move qemu_utimensat() to oslib-posix.c - Rebased on latest qemu.git v4: - Use tv_now.tv_usec v3: - Use better alternative handling for UTIME_NOW/OMIT - Move qemu_utimensat() to cutils.c V2: - Introduce qemu_utimensat() Acked-by: Chris Wright <chrisw@sous-sol.org> Acked-by: M.

* Consolidate oom_check() functionsJes Sorensen2010-10-301-5/+3
| | | | | | | | | This consolidates the duplicated oom_check() functions, as well as splitting them into OS dependant versions to avoid the #ifdef grossness that was present in the old osdep.c version.

* Move QEMU OS dependant library functions to OS specific filesJes Sorensen2010-10-301-0/+74
This moves library functions used by both QEMU and the QEMU tools, such as qemu-img, qemu-nbd etc. from osdep.c to oslib-{posix,win32}.c In addition it introduces oslib-obj.y to the Makefile set to be included by the various targets, instead of relying on these library functions magically getting included via block-obj-y.
