rtapi_div_u64 − unsigned division of a 64-bit number by a 32-bit number

__u64 rtapi_div_u64_rem(__u64 dividend, __u32 divisor, __u32 *remainder) | |

__u64 rtapi_div_u64(__u64 dividend, __u32 divisor) |
dividend
The value to be divided
divisor
The value to divide by
remainder
Pointer to the location to store the remainder. This may not be a NULL pointer. If the remainder is not desired, call rtapi_div_u64.
Perform integer division (and optionally compute the remainder) with a 64-bit dividend.
The result of integer division of dividend / divisor.
If the result of the division does not fit in a __u32, the result is undefined.
This function exists because in kernel space, the use of the division operator on a 64-bit type can lead to an undefined symbol when the module is loaded.
May be called from init/cleanup code and from within realtime tasks. Available in userspace components.
