Async IO on android >= 2.1

[Louise Cypher]

Hi

Is there any support for ASYNC io in native conde on androids >= 2.1 ?
I'v searched in headers but aio_read and such are not present, and sys/limits.h undefines _POSIX_ASYNCHRONOUS_IO, so no ASYNC IO ?

I need to constantly stream chunks of data from big resource file located on SD card, and on iPhone we use async io for this purpose, I just dont want to create another thread in my app
to do io in nonblocking way from native.

Take a look at Boost.Asio

.... android does not have asio_* so the stream part probably will be broken.

I need something that is in system, if there is no such thing i can do it myself by creating additional thread(s) to realise io requests and notify me about completion status, but i want to avoid this.

There is no aio_ support in Bionic at this point. I recommend either using threads or non-blocking i/o as an alternative.

I'm not sure what you mean, but Asio is a header only library, so you
don't need any *.so...

[David Turner]

Sorry, typo, I meant the aio_* functions like aio_open(), aio_read(), etc...

These functions are typically implemented by the C library using threads. Bionic doesn't provide them for now so you will have to do it yourself.
