NAME aio_write – asynchronous write SYNOPSIS #include <aio.h> int aio_write(struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aio_write() function queues the I/O request described by the buffer pointed to by aiocbp. This function is the asynchronous analog of write(2). The arguments of the call write(fd, buf, count) correspond (in order) to the fields aio_fildes, aio_buf,…

DESCRIPTION The aio_suspend() function suspends the calling thread until one of the following occurs: * One or more of the asynchronous I/O requests in the list…
NAME aio_return – get return status of asynchronous I/O operation SYNOPSIS #include <aio.h> ssize_t aio_return(struct aiocb *aiocbp); Link with -lrt.

NAME aio_read – asynchronous read SYNOPSIS #include <aio.h> int aio_read(struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aio_read() function queues the I/O request described by the buffer pointed to by aiocbp. This function is the asynchronous analog of read(2).

NAME aio_init – asynchronous I/O initialization SYNOPSIS #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <aio.h> void aio_init(const struct aioinit *init); Link with -lrt. DESCRIPTION The GNU-specific aio_init() function allows the caller to provide tuning hints to the glibc POSIX AIO implementation. Use of this function is optional, but to be effective, it must be called…
NAME aio_fsync – asynchronous file synchronization SYNOPSIS #include <aio.h> int aio_fsync(int op, struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aio_fsync() function does a sync on all outstanding asynchronous I/O operations associated with aiocbp->aio_fildes. (See aio(7) for a description of the aiocb structure.) More precisely, if op is O_SYNC, then all currently queued I/O operations…
NAME aio_error – get error status of asynchronous I/O operation SYNOPSIS #include <aio.h> int aio_error(const struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aio_error() function returns the error status for the asynchronous I/O request with control block pointed to by aiocbp. (See aio(7) for a description of the aiocb structure.) RETURN VALUE This function returns…
NAME aio_cancel – cancel an outstanding asynchronous I/O request SYNOPSIS #include <aio.h> int aio_cancel(int fd, struct aiocb *aiocbp); Link with -lrt. DESCRIPTION The aio_cancel() function attempts to cancel outstanding asynchronous I/O requests for the file descriptor fd. If aiocbp is NULL, all such requests are canceled. Otherwise, only the request described by the control block…
