std::string 의 formating
2009/09/15 15:34
boost 라이브러리를 쓰라는 얘기도 있지만 일단.
#include <stdarg.h>
std::string format_arg_list(const char *fmt, va_list args)
{
if (!fmt) return "";
int result = -1, length = 256;
char *buffer = 0;
while (result == -1)
{
if (buffer) delete [] buffer;
buffer = new char [length + 1];
memset(buffer, 0, length + 1);
result = vsnprintf(buffer, length, fmt, args);
length *= 2;
}
std::string s(buffer);
delete [] buffer;
return s;
}
std::string format(const char *fmt, ...)
{
va_list args;
va_start(args, fmt);
std::string s = format_arg_list(fmt, args);
va_end(args);
return s;
}

만약 gcc에서 해당 코드를 돌리려는 생각이라면
