Recently, when I write code in linux, I always need to check the definition and call relationship. It is inconvenient to switch to source insight in windows every time, so I tried ctags + cs.pdf. I only want to quickly view the definition of

[Cpp] # include static const char NumToChar [16] [2] = {0, '0'}, {1, '1'}, {2, '2 '}, {3, '3'}, {4, '4'}, {5, '5'}, {6, '6'}, {7, '7 '}, {8, '8'}, {9, '9'}, {10, 'A'}, {11, 'B'}, {12, 'C '}, {13, 'D'}, {14, 'E'}, {15, 'F'}; char num2char (char num);

Although this concept has been widely used, I still want to record it for future queries. # Ifdef _ DEBUG # define DEBUG_CLIENTBLOCK new (_ CLIENT_BLOCK, _ FILE __, _ LINE _) # else # define DEBUG_CLIENTBLOCK # endif # define _ CRTDBG_MAP_ALLOC #
