역시 RZJOIN은 인터넷에 없었군요..
저도 찾다찾다 못찾았었는데요..
잘 쓰겠습니다.. 다만 CRC체크를 해 주는 기능이 업어서 좀 불안하네요..
기능 추가해주시면 더욱 좋겠습니다..
 : 전에 하이텔에 올렸던 소스입니다. 인터넷에 올라온 동영상 파일들을 보면
: xxx.001, xxx.002 이렇게 이름 붙은 것들이 있죠? rzsplit라는 유틸리티로
: 분할한 것으로 rzjoin 유틸리티로 합칠 수 있습니다.
: 리눅스에서 어떻게 이런 파일을 합쳐볼려구 제가 어찌어찌 만들어 봤습니
: 다. 소스는 허접하지만, 지금까지 문제없이 잘 동작하네요. 어쩌다 윈도우즈
: 에서는 잘 join이 안되는 파일도 이걸로는 잘 합쳐집니다.
: -- 신기하다 --;;
:
: 아래는 소스입니다. 유닉스에서 cc -o rzjoin rzjoin.c 하면 컴팔됩니다.
: 사용법은 rzjoin xxx.001 입니다.
