IO_DESTROY(2) Linux Programmer's Manual IO_DESTROY(2)


     io_destroy - destroy an asynchronous I/O context


     #include <linux/aio_abi.h>          /* Defines needed types */
     int io_destroy(aio_context_t ctx_id);
     Note: There is no glibc wrapper for this system call; see NOTES.


     The  io_destroy()  system  call  will attempt to cancel all outstanding
     asynchronous I/O operations against ctx_id, will block on  the  comple-
     tion of all operations that could not be canceled, and will destroy the


     On success, io_destroy() returns 0.  For the failure return, see NOTES.


     EFAULT The context pointed to is invalid.
     EINVAL The AIO context specified by ctx_id is invalid.
     ENOSYS io_destroy() is not implemented on this architecture.


     The asynchronous I/O system calls first appeared in Linux 2.5.


     io_destroy()  is Linux-specific and should not be used in programs that
     are intended to be portable.


     Glibc does not provide a wrapper function for this  system  call.   You
     could  invoke  it  using syscall(2).  But instead, you probably want to
     use the io_destroy() wrapper function provided by libaio.
     Note that the libaio wrapper function uses a  different  type  (io_con-
     text_t)  for  the  ctx_id  argument.  Note also that the libaio wrapper
     does not follow the usual C library conventions for indicating  errors:
     on  error it returns a negated error number (the negative of one of the
     values  listed  in  ERRORS).   If  the  system  call  is  invoked   via
     syscall(2),  then  the  return  value follows the usual conventions for
     indicating an error: -1, with errno set  to  a  (positive)  value  that
     indicates the error.
