**Definition**: `syscInputScalarData.h` (line 40)

Provide a struct for input scalar data.

Input scalar data provides read and write access to an array of scalar data.

To create and/or initialize [SyscInputScalarData](structSyscInputScalarData.md#structSyscInputScalarData), it is highly recommended to use one of the functions with names starting with `syscGetInputScalarData`. These functions will initialize all members to the correct values and will help to avoid back-compatibility issues in the future. For example:

```
SyscInputScalarData isd = syscGetInputScalarDataDouble(array, arraySize);

```

## Members

- [data](structSyscInputScalarData.md#structSyscInputScalarData_1a1a84599e793064d8c6275084ffe16cfe)
- [primitiveType](structSyscInputScalarData.md#structSyscInputScalarData_1ab177e62c0635afebce589c1a411144fe)
- [size](structSyscInputScalarData.md#structSyscInputScalarData_1aab4ae5518bec7d42d01359b5459bf7e2)
