Function `__rndrrs`

#[target_feature(enable = "rand")]
pub unsafe fn __rndrrs(value: *mut u64) -> i32

Reseeds the random number generator. After that stores a 64-bit random number into the object pointed to by the argument and returns zero. If the implementation could not generate a random number within a reasonable period of time the object pointed to by the input is set to zero and a non-zero value is returned.
