# vDSP_vsaddi

Calculates the integer element-wise sum of a vector and a scalar value, using the specified stride.

## Declaration

```occ
extern void vDSP_vsaddi(const int *__A, vDSP_Stride __IA, const int *__B, int *__C, vDSP_Stride __IC, vDSP_Length __N);
```

## Parameters

- `__A`: The input vector, A.
- `__IA`: The distance between the elements in the input vector.
- `__B`: The input scalar, B.
- `__C`: The output vector, C.
- `__IC`: The distance between the elements in the output vector.
- `__N`: The number of elements that the function processes.

## Discussion

Discussion This function calculates the element-wise sum of vector A and scalar value B, and writes the result to vector C, as follows:  for (n = 0; n < N; ++n)     C[n] = A[n] + B;

The following code shows an example of using this function:
