curl_easy_perform() 실패 : FTP 업로드 실패 (STOR 명령) 오류

Question

"curl_easy_perform() failed : FTP 업로드 실패 (STOR 명령)"오류로 FTP 서버에 파일을 업로드하는 데 실패했습니다 .i 봤지만 많은 솔루션이나 제안을 찾을 수 없습니다. 여기에 문자 포인터가 발생하는 오류에 대한 좀 더 세부 사항이있을 것이다

설정

curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, char* allocatedMemoryForErrorBuffer); 

내 작은 코드입니다. 일반적으로이 HTTP 요청에 대해 작동하지만 내 이해뿐만 아니라 FTP 작동해야합니다.
