I am new to C++ coding, coming from Java and C# background. I\'m puzzled by the proliferation of #define terms starting with the most basic:
in my c++ linux application I have this macro: #define PRINT(format,arg...) printf(format,##arg) I want to add a date and time to the beggining of the string that come to PRINT. (it is a log, so I
#define swap(a,b,c)(int t;t=a;a=b;b=t;); void main() { int x=10,y=20; swap (x,y,int); printf(\"%d %d\\n\",x,y);
Is it possible to do something like this: #define F(x) \\ #ifdef DOUBLE \\ 2*x \\ #else \\ x \\ #endif so that when I use F, what it expands to depends on whether the macro DOUBLE is defined?I don\
I have a log statement in which I always use this.getClass().getSimpleName()as the 1st parameter. I would like to put this in some sort of macro constant and use that in all my log statements.
Note - using variadic arguments, Phix has provided a super solution below. However it gives compiler warnings when used with integers since you\'re casting them to an id, and it will not work with for
I just saw this thread, describing how to add conditional macros: Conditional value for a #define but in my case I am defining a function within the condition.
GCC supports -fshort-wchar that switches wchar_t from 4, to two bytes. What is the best way to detect the size of wchar_t at compile time, so I can map it correctly to the appropriate utf-16 or utf-3
I want a macro that create a new identifier like (new-name first second) => first-second that could be used to define new toplevel bindings
I\'m looking for generic bit macros (e.g. extracting or setting multiple bits), so that I don\'t have to reinvent them. On NetBSD I found at least 开发者_运维知识库__BIT and __BITS in <sys/cdefs.h&
