NAME
aiofsync - asynchronous file synchronization SYNOPSIS
#include
int aiofsync(int op, struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aiofsync() function does a sync on all outstanding asynchronous
I/O operations associated with aiocbp->aiofildes. (See aio(7) for a description of the aiocb structure.) More precisely, if op is OSYNC, then all currently queued I/O opera‐ tions shall be completed as if by a call of fsync(2), and if op is ODSYNC, this call is the asynchronous analog of fdatasync(2). Note that this is a request only; it does not wait for I/O completion. Apart from aiofildes, the only field in the structure pointed to by aiocbp that is used by this call is the aiosigevent field (a sigevent structure, described in sigevent(7)), which indicates the desired type of asynchronous notification at completion. All other fields are ignored. RETURN VALUE On success (the sync request was successfully queued) this function
returns 0. On error -1 is returned, and errno is set appropriately. ERRORS EAGAIN Out of resources. EBADF aiofildes is not a valid file descriptor open for writing. EINVAL Synchronized I/O is not supported for this file, or op is not OSYNC or ODSYNC. ENOSYS aiofsync() is not implemented. VERSIONS The aiofsync() function is available since glibc 2.1.
