NAME

       io_uring_prep_send - prepare a send request

SYNOPSIS

       #include <liburing.h>

       void io_uring_prep_send(struct io_uring_sqe *sqe,
                               int sockfd,
                               const void *buf,
                               size_t len,
                               int flags);

DESCRIPTION

       The io_uring_prep_send(3) function prepares a send request. The submission queue entry sqe
       is setup to use the file descriptor sockfd to start sending the data from buf of size size
       and with modifier flags flags.

       This function prepares an async send(2) request. See that man page for details.

RETURN VALUE

       None

ERRORS

       The  CQE  res field will contain the result of the operation. See the related man page for
       details on possible values. Note that where synchronous system calls  will  return  -1  on
       failure  and  set  errno to the actual error value, io_uring never uses errno.  Instead it
       returns the negated errno directly in the CQE res field.
