From 831f9f01fbe4088eb6bd378c0e417d9996b676fd Mon Sep 17 00:00:00 2001 From: scratko Date: Fri, 30 Aug 2024 12:46:56 +0300 Subject: Final version v2.0 Added windows client. SIGPIPE signal was being sent to the server when the client was disconnected. Now there is handling of this signal. Added a delay when displaying some informational messages. --- client/Makefile | 23 --- client/card_handling.c | 64 -------- client/card_handling.h | 9 -- client/card_stack.c | 173 -------------------- client/card_stack.h | 30 ---- client/client.c | 322 ------------------------------------- client/client.h | 84 ---------- client/data_decryption.c | 181 --------------------- client/data_decryption.h | 16 -- client/printing_game_frames.c | 183 --------------------- client/printing_game_frames.h | 20 --- client/verification_client_input.c | 115 ------------- client/verification_client_input.h | 12 -- 13 files changed, 1232 deletions(-) delete mode 100644 client/Makefile delete mode 100644 client/card_handling.c delete mode 100644 client/card_handling.h delete mode 100644 client/card_stack.c delete mode 100644 client/card_stack.h delete mode 100644 client/client.c delete mode 100644 client/client.h delete mode 100644 client/data_decryption.c delete mode 100644 client/data_decryption.h delete mode 100644 client/printing_game_frames.c delete mode 100644 client/printing_game_frames.h delete mode 100644 client/verification_client_input.c delete mode 100644 client/verification_client_input.h (limited to 'client') diff --git a/client/Makefile b/client/Makefile deleted file mode 100644 index 2e2ce88..0000000 --- a/client/Makefile +++ /dev/null @@ -1,23 +0,0 @@ -SRCMODULES = card_handling.c card_stack.c data_decryption.c\ - printing_game_frames.c verification_client_input.c client.c -OBJMODULES = $(SRCMODULES:.c=.o) -CC = gcc -CFLAGS = -Wall -g -c - -all: client - -%.o: %.с %.h - $(CC) $(CFLAGS) $< -o $@ - -client: $(OBJMODULES) - $(CC) $(LIBS) $^ -o $@ - -ifneq (clean, $(MAKECMDGOALS)) --include deps.mk -endif - -deps.mk: $(SRCMODULES) - $(CC) -MM $^ > $@ - -clean: - rm -f *.o client diff --git a/client/card_handling.c b/client/card_handling.c deleted file mode 100644 index 011ad40..0000000 --- a/client/card_handling.c +++ /dev/null @@ -1,64 +0,0 @@ -#include "card_handling.h" - -#include -#include - -int convert_rank_to_int(const char *card) -{ - int length;
