I need to provide configuration file, which will describe which STL header files to include. I have found that usually it is done by defining a lot of HAVE_XXX_HEADER macros. I wonder 开发者_StackOver
Sometimes, when using macros to generate code, it is necessary to create identifiers that have global scope but which aren\'t really useful for anything outside the immediate context where they are cr
I\'ve written a compiler for a general-purpose programming language that produces an optimised parse tree of its input. This intermediate format is then run through a preprocessor to translate it into
My problem is quite simple. I want the following macro #define PROXYPASS(name, param) \\ void MyClass::sl_name(param _param) { \\
I\'m trying to do some kind of Macro \"Overloading\", so that MACRO(something), gets expanded differently than MACRO(something, else).
I want to stringify the result of a macro expansion. I\'ve tried with the following: #define QUOTE(str) #str
I want to ask a question about th开发者_C百科e objective-C or may be the C language. I want to ask what is the meaning of the following code of #define? Is it like to declare a variable?
Say you have a C project with tons of files, and tons of configurations managed by using the -D option in GCC to define some flags.
I\'ve distilled my problem down to this code snippet - but it is a part of a larger program so I don\'t want a different way to do this - I need a way to make this work!
I know that I am trying to shoot myself in the leg ;) However, it will allow me to make the rest (big amount) of code smaller and more readable.
