       io_uring_prep_ftruncate - prepare an ftruncate request

СИНТАКСИС

       #include <liburing.h>

       void io_uring_prep_ftruncate(struct io_uring_sqe *sqe,
                                    int fd,
                                    loff_t len);

ОПИСАНИЕ

       The io_uring_prep_ftruncate(3) function prepares an ftruncate
       request. The submission queue entry sqe is setup to use the file
       descriptor fd that should get truncated to the length indicated
       by the len argument.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       None

ОШИБКИ

       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.
