Macro C++ Issues __VA_ARGS__
- by CodeLizard
What (if any) are some potential problems with a C++ macro usage like this?
Would an inline function be a more appropriate solution?
#define EVENT_INFO(_format_, ...) CMyEvent::Generate(__FILE__, __LINE__, CMyEvent::EVT_HIGH, _format_, __VA_ARGS__)
void
CMyEvent::Generate(
const char* file, // filename
int line, // line number
CMyEvent::LEVEL level, // severity level
const char *format, // format of the msg / data
...) // variable arguments
{
// Get a message from the pool
CMyEvent* p_msg = GetMessageFromPool();
if(p_msg != NULL)
{
va_list arguments; // points to each unnamed argument
va_start(arguments, format);
// Fill the object with strings and data.
p_msg->Fill(file, line, level, 0, format, arguments);
va_end(arguments);
}
}
