hi all,
> for SuSE you need packets: libaio, libaio-devel
On SuSE 8.2 Professional I installed libaio and libaio-devel.
Any idea when the manual pages will be written and what aio library functions
are delivered via libaio ?
I checked all symbols from /usr/lib/libaio.so.1
I haven't found any POSIX based implementation aka:
aio_cancel()
Cancel an asynchronous I/O operation
aio_error()
Get the error status for an asynchronous I/O operation
aio_fsync()
Asynchronously synchronize a file
aio_read()
Asynchronously read from a file
aio_return()
Get the return status for an asynchronous I/O operation
aio_suspend()
Wait for asynchronous I/O operations to complete
aio_write()
Asynchronously write to a file
nor kaio ( kernel AIO )
From the libaio library:
00000000 A LIBAIO_0.1
00001534 a _DYNAMIC
000015ac a _GLOBAL_OFFSET_TABLE_
000015b8 a __bss_start
000015b8 a _edata
000015b8 a _end
00000430 T io_cancel
000004f0 T io_getevents
000003e0 T io_queue_init
00000520 T io_queue_release
00000470 T io_queue_run
00000450 T io_queue_wait
00000410 T io_submit
Any idea on what the libaio is based on and where can we get more info about
the current implementation of the library ? How can I check if my system
support KAIO or just userland AIO ?
Many thanks,
Stefan
