The second macro is va_arg. You call it with a va_list and a type, and it takes value pointed at by the va_list as a value of the given type, then increment the pointer by the size of that pointer. Maybe because you might have a varargs function prototype which doesn't actually care about the varargs and setting up varargs happens to be expensive on that particular system. Maybe because of more complex operations where you do va_copy or maybe you want to restart working with the arguments multiple times and call va_start multiple times.

2016-11-23 · How do varargs work in C? When I was taught C, functions had a fixed number of arguments. Here’s an example: int sum_squares(int a, int b) { return a*a + b*b; } Function arguments are placed on the stack. So executing sum_squares(2,3) means placing 2 and 3 (amongst some other things) on the stack.

Don't use varargs (ellipsis) Summary Ellipses cause collapses: The ellipsis is a dangerous carryover from C.

The vararg C++ attribute has the same functionality as the vararg MIDL attribute. Example. The following code shows a use of vararg: In ANSI C, the head of a varargs function looks just like its prototype. stripped-down version of printf. The bare outline of the function definition will look like this: void myprintf(const char *fmt,) printf's job, of course, The C standard mandates that the only place the identifier __VA_ARGS__ can appear is in the replacement list of a variadic macro. It may not be used as a macro name, macro argument name, or within a different type of macro. It may also be forbidden in open text; the standard is ambiguous.

Exceptions. DCL50-CPP-EX1: It is permissible to define a C-style variadic function if that function also has external C language linkage.For instance, the function may be a definition used in a C library API that is implemented in C++. DCL50-CPP-EX2: As stated in the normative text, C-style variadic functions that are declared but never defined are permitted.

D) None. Answer [=] B. Explanation: Yes. The compiler throws errors "Unresolved Compilation Problem" and "The variable argument type of the method or constructor must be the last parameter" In fact, support for varargs is an often requested feature that was first added in SWIG-1.3.12. Most other wrapper generation tools have wisely chosen to avoid this issue.

Note also that the varargs interface used * to pass tag types and values uses the NB: ttag_t is unsigned int and not unsigned short because * ANSI C requires 

* * Programs written in C can use these preprocessor definitions to  #else #include /* Technically illegal; va_alist should be only arg */ extern void vderror(fmt,va_alist) const char* fmt; va_dcl; extern void vdwarn(fmt  #endif /* TFILE types */ #define TF_NULL 0 #define TF_QUEUE 1 tfout) #define oputa(aline) tfputa(aline, tfout) #define tfputc(c, file) fputc((c),  + 16. - 3. log/log.c Visa fil append the varargs to the buffer we want to print.

To declare a variadic function, an ellipsis appears after the list of parameters, e.g. int printf (const char * format In C programming, variadic function will contribute to the flexibility of the program that you are developing.
