| ``` |

| ## Usage |
| |
| ```js |
| var isUncPath = require('is-unc-path'); |
| ``` |
| |
| **true** |
| |
| Returns true for windows UNC paths: |
| |
| ```js |
| isUncPath('\\/foo/bar'); |
| isUncPath('\\\\foo/bar'); |
| isUncPath('\\\\foo\\admin$'); |
| isUncPath('\\\\foo\\admin$\\system32'); |
| isUncPath('\\\\foo\\temp'); |
| isUncPath('\\\\/foo/bar'); |
| isUncPath('\\\\\\/foo/bar'); |
| ``` |
| |
| **false** |
| |
| Returns false for non-UNC paths: |
| |
| ```js |
| isUncPath('/foo/bar'); |
| isUncPath('/'); |
| isUncPath('/foo'); |
| isUncPath('/foo/'); |
| isUncPath('c:'); |
| isUncPath('c:.'); |
| isUncPath('c:./'); |
| isUncPath('c:./file'); |
| isUncPath('c:/'); |
| isUncPath('c:/file'); |
| ``` |
| |
| **Customization** |
| |
| Use `.source` to use the regex as a component of another regex: |
| |
| ```js |
| var myRegex = new RegExp(isUncPath.source + 'foo'); |
| ``` |

| |
| * The computer name is always preceded by a double backward-slash (`\\`). |
| * UNC paths cannot contain a drive letter (such as `D:`) |
