# Contiguous Data Buffer
> Create a zero-filled contiguous linear ndarray data buffer.
## Usage
```javascript
var buffer = require( '@stdlib/ndarray/base/buffer' );
```
#### buffer( dtype, size )
Returns a zero-filled contiguous linear ndarray data buffer.
```javascript
var buf = buffer( 'float64', 3 );
// returns [ 0.0, 0.0, 0.0 ]
```
The function supports the following data types:
- `binary`: binary.
- `complex64`: single-precision complex floating-point numbers.
- `complex128`: double-precision complex floating-point numbers.
- `float32`: single-precision floating-point numbers.
- `float64`: double-precision floating-point numbers.
- `generic`: values of any type.
- `int16`: signed 16-bit integers.
- `int32`: signed 32-bit integers.
- `int8`: signed 8-bit integers.
- `uint16`: unsigned 16-bit integers.
- `uint32`: unsigned 32-bit integers.
- `uint8`: unsigned 8-bit integers.
- `uint8c`: unsigned clamped 8-bit integers.
If provided an unknown or unsupported data type, the function returns `null`.
```javascript
var buf = buffer( 'float', 3 );
// returns null
```
## Examples
```javascript
var dtypes = require( '@stdlib/ndarray/dtypes' );
var buffer = require( '@stdlib/ndarray/base/buffer' );
var DTYPES = dtypes();
var buf;
var i;
for ( i = 0; i < DTYPES.length; i++ ) {
buf = buffer( DTYPES[ i ], 10 );
console.log( buf );
}
