Zero
Fills the memory data of the destination address with zeros.
The function interface declaration is as follows:
- Operations on integers:
HmppResult HMPPS_Zero_8u(uint8_t* dst, int32_t len);
HmppResult HMPPS_Zero_16s(int16_t *dst, int32_t len);
HmppResult HMPPS_Zero_32s(int32_t *dst, int32_t len);
HmppResult HMPPS_Zero_64s(int64_t* dst, int32_t len);
HmppResult HMPPS_Zero_16sc(Hmpp16sc* dst, int32_t len);
HmppResult HMPPS_Zero_32sc(Hmpp32sc* dst, int32_t len);
HmppResult HMPPS_Zero_64sc(Hmpp64sc* dst, int32_t len);
- Operations on floating-point numbers:
HmppResult HMPPS_Zero_32f(float *dst, int32_t len);
HmppResult HMPPS_Zero_64f(double *dst, int32_t len);
HmppResult HMPPS_Zero_32fc(Hmpp32fc *dst, int32_t len);
HmppResult HMPPS_Zero_64fc(Hmpp64fc* dst, int32_t len);

Error Codes

Description |
|---|---|
HMPP_STS_NULL_PTR_ERR |
The value of 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 dst[BUFFER_SIZE_T];
int32_t i;
HmppResult result = HMPPS_Zero_8u(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 = 0 0 0 0 0 0 0 0 0 0
