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