+
+This function writes @var{length} bytes of random data to the array
+starting at @var{buffer}. On success, this function returns the number
+of bytes which have been written to the buffer (which can be less than
+@var{length}). On error, @code{-1} is returned, and @code{errno} is
+updated accordingly.
+
+The @code{getrandom} function is declared in the header file
+@file{sys/random.h}. It is a GNU extension.
+
+The following flags are defined for the @var{flags} argument:
+
+@table @code
+@item GRND_RANDOM
+Use the blocking pool instead of the non-blocking pool to obtain
+randomness. By default, the non-blocking pool is used. The blocking
+pool corresponds to @file{/dev/random}, and the non-blocking pool to
+@file{/dev/urandom}.
+
+@item GRND_NONBLOCK
+Instead of blocking, return to the caller immediately if no data is
+available.
+@end table
+
+The @code{getrandom} function is a cancellation point.
+
+Even access to the non-blocking pool can block if the system has just
+booted and the pool has not yet been initialized.
+
+The @code{getrandom} function can fail with several errors, some of
+which are listed below. In addition, the function may not fill the
+buffer completely and return a value less than @var{length}.
+
+@table @code
+@item ENOSYS
+The kernel does not implement the @code{getrandom} system call.
+
+@item EAGAIN
+No random data was available and @code{GRND_NONBLOCK} was specified in
+@var{flags}.
+
+@item EFAULT
+The combination of @var{buffer} and @var{length} arguments specifies
+an invalid memory range.
+
+@item EINTR
+The system call was interrupted. During the system boot process, before
+the kernel randomness pool is initialized, this can happen even if
+@var{flags} is zero.
+
+@item EINVAL
+The @var{flags} argument contains an invalid combination of flags.
