called from debug_DisplayError unless overridden by means of ah_display_error.
| Status sys_get_proxy_config | ( | const std::wstring & | url, |

get the proxy address for accessing the given HTTP URL.
this may be very slow (tens of seconds).
| std::wstring sys_get_user_name | ( | ) |
| bool sys_IsDebuggerPresent | ( | ) |
| size_t sys_max_sector_size | ( | ) |
return the largest sector size [bytes] of any storage medium (HD, optical, etc.) in the system.
this may be a bit slow to determine (iterates over all drives), but caches the result so subsequent calls are free. (caveat: device changes won't be noticed during this program run)
sector size is relevant because Windows aio requires all IO buffers, offsets and lengths to be a multiple of it. this requirement is also carried over into the vfs / file.cpp interfaces for efficiency (avoids the need for copying to/from align buffers).
waio uses the sector size to (in some cases) align IOs if they aren't already, but it's also needed by user code when aligning their buffers to meet the requirements.
the largest size is used so that we can read from any drive. while this is a bit wasteful (more padding) and requires iterating over all drives, it is the only safe way: this may be called before we know which drives will be needed, and hardlinks may confuse things.
| Status sys_open_url | ( | const std::string & | url | ) |
| FILE* sys_OpenFile | ( | const OsPath & | pathname, |
| const char * | mode | ||
| ) |
describe the current OS error state.
| err,: | if not 0, use that as the error code to translate; otherwise, uses GetLastError or similar. |
| buf | output buffer |
| max_chars | rationale: it is expected to be rare that OS return/error codes are actually seen by user code, but we leave the possibility open. |
