C++ (Cpp) vararg Examples

Example #1

File: vararg-8-nov.c Project: 0day-ci/gcc

void foo (int *p, ...)
{
  va_list args;

  va_start (args, p);
  vararg (p, args);
  va_end (args);
}

Example #2

File: 20030811-1.c Project: alpine9000/BitOS

void test1 (void)
{
  int a = (int) (long long) __builtin_return_address (0);
  vararg (0, a);
}

Example #3

File: vararg-non-pod.cpp Project: ACSOP/android_external_clang

// CHECK: define void @_Z4test1X
void test(X x) {
  // CHECK: call void @llvm.trap()
  vararg(x);
  // CHECK: ret void
}

Example #4

File: varargs.c Project: Abocer/android-4.2_r1

void function_as_vararg() {
  // CHECK: define {{.*}}function_as_vararg
  // CHECK-NOT: llvm.trap
  vararg(0, focus_changed_cb);
}

Example #5

File: p7-0x.cpp Project: ACSOP/android_external_clang

void f(X1 x1, X2 x2) {
  vararg(x1); // okay
  vararg(x2); // expected-error{{cannot pass object of non-trivial type 'X2' through variadic function; call will abort at runtime}}
}

Example #6

File: p7-0x.cpp Project: AndroidMarv/clang

void f(X1 x1, X2 x2, X3 x3, X4 x4) {
  vararg(x1); // OK
  vararg(x2); // expected-error{{cannot pass object of non-trivial type 'X2' through variadic function; call will abort at runtime}}
  vararg(x3); // OK
  vararg(x4); // expected-error{{cannot pass object of non-trivial type 'X4' through variadic function; call will abort at runtime}}
}
