我有这个功能:
void Log::Write(string logline){
//2011-10-12 13:07:40 correct format
time_t rawtime;
struct tm * timeinfo;
time ( &rawtime );
timeinfo = localtime ( &rawtime );
m_stream.write( asctime (timeinfo), 24 );
m_stream << " - " << logline << std::endl;
}
输出如下:
但我想看到输出类似于注释部分:
这怎么可能?
最佳答案
这很有可能。查看联机帮助页中的strftime()
。在这种情况下,您需要:
void Log::Write(string line)
{
time_t rawtime;
struct tm * timeinfo;
char buffer [80];
time ( &rawtime );
timeinfo = localtime ( &rawtime );
strftime (buffer,80,"%Y-%m-%d %H:%M:%S",timeinfo);
m_stream << buffer << " - " << line << endl;
}
