| 17 | // Portable error handling functions. This is only necessary for host-side |
| 18 | // code that needs to be cross-platform; code that is only run on Unix should |
| 19 | // just use errno and strerror() for simplicity. |
| 20 | // |
| 21 | // There is some complexity since Windows has (at least) three different error |
| 22 | // numbers, not all of which share the same type: |
| 23 | // * errno: for C runtime errors. |
| 24 | // * GetLastError(): Windows non-socket errors. |
| 25 | // * WSAGetLastError(): Windows socket errors. |
| 26 | // errno can be passed to strerror() on all platforms, but the other two require |
| 27 | // special handling to get the error string. Refer to Microsoft documentation |
| 28 | // to determine which error code to check for each function. |
