[c/c++] SMI를 SRT로 컨버팅하기

윈도버전

컴파일 시 큰 문제는 없는데, 대입하는 포인터의 형이 달라서 경고가 뜨는 경우가 있다는데, 내 경우에는 윈도에서 컴파일시 오류가 났다. char* 형에대해 메모리를 할당할 때 캐스팅을하지 않으면 void*로 취급하므로 오류가 나면서 컴파일이 안됐다. 수정~

맥버전

윈도 버전에서 추가 수정. 문자열을 대문자로 변환하면서 사용된 strupr() 함수는 윈도우용 gcc에 포함된 것으로 보이는 함수이다. 아마 문자열을 대문자로 만들어주는 함수로 보이는데, C표준함수는 아니어서 맥에서는 존재하지 않는 심벌이라는 오류를 내면서 컴파일 되지 않는다.

따라서 이 부분을 대체할 수 있도록 strupr 함수를 추가로 작성했다. 아래 함수를 위 코드에 더하거나 include하여 컴파일하면 성공~

#include <ctype.h>

void strupr(char *somestr)
{
	while(*(somestr+i)!='\0')
	{
		*(somestr+i) = toupper(*(somestr+i));
		somestr++;
	}
}
