aio_group_completion_np(3) Library Functions Manual aio_group_completion_np(3) NAME aio_group_completion_np - Enable the use of aio_results_np function SYNOPSIS #include <aio.h> int aio_group_completion_np ( void ); PARAMETERS None. DESCRIPTION The aio_group_completion_np function enables an application to use aio group completion through the aio_result_np function. The function must be called before any other aio function. After this call, the use of the aio_error and aio_return functions becomes unde- fined, and they may return unexpected errors. The best practice is never to intermix the two forms of aio completion. Calling the func- tion after the use of any other aio function will result in failure. RETURN VALUES If the function returns successfully, the number of completed aio oper- ations reported on is returned. That is, the return value is the num- ber of valid entries in in the array. If the value returned is the same as the nent argument, more aio operations may be complete and can be reported on by another call to aio_results_np. On an unsuccessful call, a value of -1 is returned and errno is set to indicate that an error occurred. ERRORS The aio_group_completion_np function fails under the following condi- tions: Another aio function has already been called. Inadequate system resources exist to enable group completion at this time.
