NAME
io_setup - create an asynchronous I/O contextSYNOPSIS
#include <libaio.h> int io_setup(unsigned nr_events, aio_context_t *ctxp); Link with -laio.
DESCRIPTION
io_setup() creates an asynchronous I/O context capable of receiving at least nr_events. ctxp must not point to an AIO context that already exists, and must be initialized to 0 prior to the call. On successful creation of the AIO context, *ctxp is filled in with the resulting handle.
RETURN VALUE
io_setup() returns 0 on success; on failure, it returns one of the errors listed under ERRORS.
ERRORS
- EINVAL
- ctxp is not initialized, or the specified nr_events exceeds internal limits. nr_events should be greater than 0.
- EFAULT
- An invalid pointer is passed for ctxp.
- ENOMEM
- Insufficient kernel resources are available.
- EAGAIN
- The specified nr_events exceeds the user's limit of available events.
- ENOSYS
- io_setup() is not implemented on this architecture.
VERSIONS
The asynchronous I/O system calls first appeared in Linux 2.5, August 2002.
CONFORMING TO
io_setup() is Linux-specific and should not be used in programs that are intended to be portable.
