From 308ba2d96d3dc0e49821c9db9902882e3919e372 Mon Sep 17 00:00:00 2001 From: Ilari Liusvaara Date: Wed, 9 Nov 2011 00:37:44 +0200 Subject: [PATCH 3/7] Don't use time() in emulating chips Instead of using time() in chip emulation, create new interface method currentTime(), defaulting to time(0). This way frontend can cleanly override the current time bsnes is using. --- snes/chip/bsx/satellaview/satellaview.cpp | 2 +- snes/chip/spc7110/spc7110.cpp | 2 +- snes/chip/srtc/srtc.cpp | 2 +- snes/interface/interface.cpp | 5 +++++ snes/interface/interface.hpp | 1 + 5 files changed, 9 insertions(+), 3 deletions(-) diff --git a/snes/chip/bsx/satellaview/satellaview.cpp b/snes/chip/bsx/satellaview/satellaview.cpp index 7bfd13f..b2565ea 100755 --- a/snes/chip/bsx/satellaview/satellaview.cpp +++ b/snes/chip/bsx/satellaview/satellaview.cpp @@ -39,7 +39,7 @@ uint8 BSXSatellaview::mmio_read(unsigned addr) { if(counter == 0) { time_t rawtime; - time(&rawtime); + rawtime = SNES::interface->currentTime(); tm *t = localtime(&rawtime); regs.r2192_hour = t->tm_hour; diff --git a/snes/chip/spc7110/spc7110.cpp b/snes/chip/spc7110/spc7110.cpp index 835ddbb..f5463e5 100755 --- a/snes/chip/spc7110/spc7110.cpp +++ b/snes/chip/spc7110/spc7110.cpp @@ -102,7 +102,7 @@ void SPC7110::set_data_adjust(unsigned addr) { r4814 = addr; r4815 = addr >> 8; void SPC7110::update_time(int offset) { time_t rtc_time = (rtc[16] << 0) | (rtc[17] << 8) | (rtc[18] << 16) | (rtc[19] << 24); - time_t current_time = time(0) - offset; + time_t current_time = SNES::interface->currentTime() - offset; //sizeof(time_t) is platform-dependent; though rtc[] needs to be platform-agnostic. //yet platforms with 32-bit signed time_t will overflow every ~68 years. handle this by diff --git a/snes/chip/srtc/srtc.cpp b/snes/chip/srtc/srtc.cpp index 1dd8f86..b11b756 100755 --- a/snes/chip/srtc/srtc.cpp +++ b/snes/chip/srtc/srtc.cpp @@ -32,7 +32,7 @@ void SRTC::reset() { void SRTC::update_time() { time_t rtc_time = (rtc[16] << 0) | (rtc[17] << 8) | (rtc[18] << 16) | (rtc[19] << 24); - time_t current_time = time(0); + time_t current_time = SNES::interface->currentTime(); //sizeof(time_t) is platform-dependent; though rtc[] needs to be platform-agnostic. //yet platforms with 32-bit signed time_t will overflow every ~68 years. handle this by diff --git a/snes/interface/interface.cpp b/snes/interface/interface.cpp index a0e3a81..b3017c9 100755 --- a/snes/interface/interface.cpp +++ b/snes/interface/interface.cpp @@ -18,4 +18,9 @@ void Interface::message(const string &text) { print(text, "\n"); } +time_t Interface::currentTime() +{ + return time(0); +} + } diff --git a/snes/interface/interface.hpp b/snes/interface/interface.hpp index f1a48c0..df975e8 100755 --- a/snes/interface/interface.hpp +++ b/snes/interface/interface.hpp @@ -5,6 +5,7 @@ struct Interface { virtual string path(Cartridge::Slot slot, const string &hint) = 0; virtual void message(const string &text); + virtual time_t currentTime(); }; extern Interface *interface; -- 1.7.9.48.g85da4d
