and the check for macro calls continues. Therefore, the actual arguments can contain calls to other macros, either with or without arguments, or even to the same macro. The macro body can also contain calls to other macros. For example,`min (min...

翻译: 19.4 C macros shall only expand to a braced initialiser, a constant, a parenthesized expression, a type qualifier, a storage class specifier, or a do-while-zero construct. 翻译: 19.5 Macros shall not be #define’d or #undef’d within a block. 翻译: 19.6 #undef shall not be used...
You may want to emulate this system by defining macros for your own libraries. This implies that you have to define a compiler switch (analogous toBUILDLIB) yourself. This can be done with -D flag of Oracle Developer Studio C/C++ compilers. Using -D option at command line is equivalent ...
2. Using gcc, you can define macros and decide the course of your programming. For example, if I wish to perform debugging. I will define __DEBUG__ through gcc.To define macros using gcc, compile using the D option of gcc gcc -Dmacro[=defn]...] ...
This header file just defines macros for malloc, realloc and free, and by default libc malloc(), realloc() and free() are used. Just edit this file in order to change the name of the allocation functions. The program using SDS can call the SDS allocator in order to manipulate SDS ...
Section 4 gives insight into the interface macros used for writing the wrapper3code. Section 5gives details of how the shared library is built which is used for loadingthe external C functions.Generation of Icon/Unicon stubs and passing them back toUnicon is given in Section 6. After that, ...
Macros shall not be #undef’d within a block. 19.6 #undef shall not be used. #undef shall not be used. 19.7 A function should be used in preference to a function like-macro. A function should be used in preference to a function like-macro Message on all function-like macro definitions...
--- SCOPE All caxe macros are scoped logically with {} and () together with some caxe specific scoping mechanisms explained later ${} and $(). A macro can be given one of 5 scope modifiers: - local [default] - file (macro visible to whole file) - global (macro visible to whole...
