With the attached code I get
C:\Dev-Cpp\Projects\test-stlport\main_19.cpp In function `void test_19(long
unsigned int)':
8 C:\Dev-Cpp\Projects\test-stlport\main_19.cpp [Warning] will never be executed
8 C:\Dev-Cpp\Projects\test-stlport\main_19.cpp [Warning] will never be executed
and when I uncomment the "i = 1" I get
C:\Dev-Cpp\Projects\test-stlport\main_19.cpp In function `void test_19(long
unsigned int)':
10 C:\Dev-Cpp\Projects\test-stlport\main_19.cpp [Warning] will never be
executed
void test_19(unsigned long ul_reason_for_call)
{
int i = 0;
switch (ul_reason_for_call)
{
case 1:
//i = 1;
break;
case 2:
break;
case 3:
break;
case 4:
break;
}
}
Happend when compiled C and C++.
