In my C++ header file, I have the following: #ifdef _DLL #define DLL_API __declspec(dllexpor开发者_运维知识库t) // Being compiled as a DLL.
开发者_如何学JAVAI was just curious to know if it is possible to have a pointer referring to #define constant. If yes, how to do it?The #define directive is a directive to the preprocessor, meaning th
Here\'s my scenario: I have a set of source files that I\'d prefer to not modify, but I\'d like to replace some of the string literals with other values.Here\'s an example:
I use to go through C code having lot of #ifdef, #if and #endif directive w开发者_Go百科hich keep some portion active and some portion inactive depending on some variables are defined or not. I search
I am trying to create a define like this #define ICONS[NSArray arrayWithObjects: [NSNumber numberWithFloat:33.0f], [NSNumber numberWithFloat:93.0f], [NSNumber numberWithFloat:149.0f], [NSNumber numbe
First off, I want it to stop on warnings.But I also want to print out some informative messages (like "Come back and implement this!").
#include <开发者_StackOverflow;stdio.h> #define f(a,b) a##b #define g(a)#a #define h(a) g(a) int main()
Is it possible to create pointer using #define? Something like this: #define *HEY I\'ll u开发者_运维百科se it for something like this:
How useful is the C++ preprocessor, really? Even in C#, it still has some functionality, but I\'ve been thinking of ditching its use altogether for a hypothetical future language. I guess that there a
It\'s possible to do certain types of type-generic-functions as macros in C, 开发者_StackOverflow社区for instance things like:
