Name Function
eq boolean s32_eq(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is equal to the second argument,
otherwise FALSE. (arg1 == arg2).
ne boolean s32_ne(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is not equal to the second
argument, otherwise FALSE. (arg1 != arg2).
gt boolean s32_gt(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is greater than the second
argument, otherwise FALSE. (arg1 > arg2).
lt boolean s32_lt(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is less than the second argument,
otherwise FALSE. (arg1 < arg2).
ge boolean s32_ge(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is greater than or equal to the
second argument, otherwise FALSE. (arg1 >= arg2).
le boolean s32_le(const s32_type *arg1,
const s32_type *arg2);
Returns TRUE if the first argument is less than or equal to the second
argument, otherwise FALSE. (arg1 <= arg2).
cmp int s32_cmp(const s32_type *arg1, const s32_type *arg2);
Returns +1 if the first argument is greater than the second argument, -1
if it is less, and 0 if it is equal.
