From 7f1ee9dad024e432fce5ffdc3a522c60169555ec Mon Sep 17 00:00:00 2001 From: Arnavion Date: Sun, 11 Oct 2015 21:34:51 -0700 Subject: common: Moved some functions over from plugins/sysinfo that are useful for the rest of HC. OS name, CPU, GPU, HDD info and build arch are now all available within core HC. OS name and build arch are used in the About dialog. --- src/common/sysinfo/sysinfo.h | 13 + src/common/sysinfo/win32/backend.c | 478 +++++++++++++++++++++++++++++++++++++ 2 files changed, 491 insertions(+) create mode 100644 src/common/sysinfo/sysinfo.h create mode 100644 src/common/sysinfo/win32/backend.c (limited to 'src/common/sysinfo') diff --git a/src/common/sysinfo/sysinfo.h b/src/common/sysinfo/sysinfo.h new file mode 100644 index 00000000..d63bf9d8 --- /dev/null +++ b/src/common/sysinfo/sysinfo.h @@ -0,0 +1,13 @@ +#ifndef HEXCHAT_SYSINFO_H +#define HEXCHAT_SYSINFO_H + +#include + +int sysinfo_get_cpu_arch (void); +int sysinfo_get_build_arch (void); +char *sysinfo_get_cpu (void); +char *sysinfo_get_os (void); +void sysinfo_get_hdd_info (guint64 *hdd_capacity_out, guint64 *hdd_free_space_out); +char *sysinfo_get_gpu (void); + +#endif diff --git a/src/common/sysinfo/win32/backend.c b/src/common/sysinfo/win32/backend.c new file mode 100644 index 00000000..c4e686a7 --- /dev/null +++ b/src/common/sysinfo/win32/backend.c @@ -0,0 +1,478 @@ +/* HexChat + * Copyright (c) 2011-2012 Berke Viktor. + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
