io_uring_prep_ftruncate(3) liburing Manual io_uring_prep_ftruncate(3)
io_uring_prep_ftruncate - prepare an ftruncate request
#include <liburing.h>
void io_uring_prep_ftruncate(struct io_uring_sqe *sqe,
int fd,
loff_t len);
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.
None
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.
