+.SH NAME
+io_uring_prep_getdents - prepare getdents64 call
+
+.SH SYNOPSIS
+.nf
+.BR "#include <liburing.h>"
+.PP
+.BI "void io_uring_prep_getdents(struct io_uring_sqe *sqe,"
+.BI " int fd,"
+.BI " void *buf,"
+.BI " unsigned int count,"
+.BI " uint64_t offset)"
+
+.SH DESCRIPTION
+.PP
+The io_uring_prep_getdents() prepares a getdents64 request. The submission queue
+entry
+.I sqe
+is setup to use the file descriptor
+.I fd
+to start writing up to
+.I count
+bytes into the buffer
+.I buf
+starting at
+.I offset.
+
+After the getdents call has been prepared it can be submitted with one of the submit
+functions.
+
+.SH RETURN VALUE
+None
+
+.SH EXAMPLE
+A getdents io_uring call can be prepared like in the following code snippet.
+The io_uring_sqe_set_data(3) call is not necessary, but it helps to correlate the
+request with the results.
