CombineHash

The function interface declaration is as follows:

HmppResult HMPPS_CombineHash(const int64_t *src1, const int64_t *src2, int32_t len, int64_t *dst);

Parameters

Parameter	Description	Value Range	Input/Output
src1	Pointer to the source vector	The value cannot be NULL.	Input
src2	Pointer to the source vector	The value cannot be NULL.	Input
len	Vector length	(0, INT_MAX]	Input
dst	Pointer to the result	The value cannot be NULL.	Output

Return Value

Success: HMPP_STS_NO_ERR
Failure: An error code is returned.

Error Codes

Error Code	Description
HMPP_STS_NULL_PTR_ERR	The value of src1, src2, or dst is NULL.
HMPP_STS_SIZE_ERR	The value of len is less than or equal to 0.

Example

#include <stdio.h>
#include "hmpp.h"
#define BUFFER_SIZE_T 10

int main() {
    int64_t src1[BUFFER_SIZE_T] = {3, 6, 2, 8, 3, 15, 56, 31, 1, 23};
    int64_t dst[BUFFER_SIZE_T] = {0};
    int64_t src2[BUFFER_SIZE_T] = {33, 612, 224, 80, 3234, 150, 562, 311, 11, 232};
    HmppResult result = HMPPS_CombineHash(src1, src2, BUFFER_SIZE_T, dst);
    printf("result = %d\n", result);
    if (result != HMPP_STS_NO_ERR) {
        return 0;
    }
    for (int i = 0; i < BUFFER_SIZE_T; i++) {
	printf("%d, ", dst[i]);
    }
    printf("\n");
}

Output:

result = 0
126, 798, 286, 328, 3327, 615, 2298, 1272, 42, 945,
