Move

Transfers data from the source address to the destination address.

The function interface declaration is as follows:

  • Operations on integers:

    HmppResult HMPPS_Move_8u(const uint8_t* src, uint8_t* dst, int32_t len);

    HmppResult HMPPS_Move_16s(const int16_t *src, int16_t *dst, int32_t len);

    HmppResult HMPPS_Move_32s(const int32_t *src, int32_t *dst, int32_t len);

    HmppResult HMPPS_Move_64s(const int64_t* src, int64_t* dst, int32_t len);

    HmppResult HMPPS_Move_16sc(const Hmpp16sc* src, Hmpp16sc* dst, int32_t len);

    HmppResult HMPPS_Move_32sc(const Hmpp32sc* src, Hmpp32sc* dst, int32_t len);

    HmppResult HMPPS_Move_64sc(const Hmpp64sc* src, Hmpp64sc* dst, int32_t len);

  • Operations on floating-point numbers:

    HmppResult HMPPS_Move_32f(const float *src, float *dst, int32_t len);

    HmppResult HMPPS_Move_64f(const double* src, double* dst, int32_t len);

    HmppResult HMPPS_Move_32fc(const Hmpp32fc *src, Hmpp32fc *dst, int32_t len);

    HmppResult HMPPS_Move_64fc(const Hmpp64fc* src, Hmpp64fc* dst, int32_t len);

Parameters

Parameter

Description

Value Range

Input/Output

src

Pointer to the source vector

The value cannot be NULL.

Input

dst

Pointer to the destination vector

The value cannot be NULL.

Output

len

Vector length

(0,INT_MAX]

Input

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 src or dst is NULL.

HMPP_STS_SIZE_ERR

The value of len is less than or equal to 0.

Example

#define BUFFER_SIZE_T 10

int main()
{
    uint8_t src[BUFFER_SIZE_T] = {1, 63, 9, 71, 3, 43, 41, 255, 0, 127};
    uint8_t dst[BUFFER_SIZE_T];
    int32_t i;

    HmppResult result = HMPPS_Move_8u(src, dst, BUFFER_SIZE_T);
    printf("result = %d \ndst =", result);
    for (i = 0; i < BUFFER_SIZE_T; i++) {
        printf(" %d    ", dst[i]);
    }

    return 0;
}

Output:

result = 0
dst = 1    63    9    71    3    43    41    255    0    127
