|IO_DESTROY(2)||Linux Programmer's Manual||IO_DESTROY(2)|
#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 completion of all operations that could not be canceled, and will destroy the ctx_id.
- The context pointed to is invalid.
- The AIO context specified by ctx_id is invalid.
- io_destroy() is not implemented on this architecture.
Note that the libaio wrapper function uses a different type (io_context_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.
