Subject: [Qemu-devel] [PATCH V2 0/6] libqblock, qemu block layer library
Date: Mon, 10 Sep 2012 16:26:20 +0800 [thread overview]
Message-ID: <1347265586-17698-1-git-send-email-xiawenc@linux.vnet.ibm.com> (raw)
This patch introduce libqblock API, make libqblock.la and make check-libqblock
could build this library.
Functionalities:
1 create a new image.
2 sync access of an image.
3 basic image information retrieving such as backing file.
4 detect if a sector is allocated in an image.
Supported Formats:
ALL using file protocols.
v2:
Insert reserved bytes into union.
Use uint64_t instead of size_t, offset.
Use const char * in filename pointer.
Initialization function removed and it was automatically executed when
library is loaded.
Added compile flag visibility=hidden, to avoid name space pollution.
Structure naming style changed.
Using byte unit instead of sector for every API.
Added a member in image static information structure, to report logical
sector size, which is always 512 now.
Read and write API can take request not aligned to 512 now. It returns the
byte number that have succeed in operation, but now neither negative value
or the number requested would be returned, because qemu block sync I/O API
would not return such number.
Typo fix due to comments and improved documents.
