[PATCH v2 0/1] MR10005: Draft: [RFC] server: Add option to return ticks since wineserver start.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=59287 - Unsure if there is a better way to make this configurable? - Is adding the message to GetTickCount ok for performance reasons? How can a user be better warned if they have an uptime above 25 days and their application uses this Api? -- v2: Draft: server: Add option to return ticks since wineserver start. https://gitlab.winehq.org/wine/wine/-/merge_requests/10005

I'd propose changes in `server/request.c` in following way: ```diff --- a/server/request.c +++ a/server/request.c /* return a monotonic time counter */ timeout_t monotonic_counter(void) { + if (serverboottime) return current_time - server_start_time; #ifdef __APPLE__ static mach_timebase_info_data_t timebase;
``` Thanks for taking a look. I also like a smaller change, but that would give a `warning: ISO C90 forbids mixed declarations and code`. I tried reducing the changed lines in `send_client_fd` in v2.
