and I need to know if MSC supports:
#pragma off (unreferenced) /* to disable unused variable warnings */
#pragma on (unreferenced) /* to enable unused variable warnings */
or at least silently ignores them.
Can someone using MS[V]C check it?
With MSVC 2008:
#include "stdafx.h"
void warn()
{
int i;
}
void badpragma()
{
#pragma off (unreferenced)
int i;
#pragma on (unreferenced)
}
int main(int argc, char * argv[])
#pragma warning( push )
#pragma warning( disable : 4101 )
{
int i;
printf("Hello, pragma test");
return 0;
}
#pragma warning( pop )
results in:
