在 C 中连接路径和文件名

Question

我有以下代码，但我需要将路径与文件名连接起来才能创建完整路径。我是 C 语言新手，只听说过 sprintf 函数。有任何想法吗？谢谢!

typedef enum{
    KeyFileRes_NewKeyFound,
    KeyFileRes_NoKeyFound
}   eKeyFileRes;

#pragma pack(push)
#pragma pack(1)

typedef struct
{
    char Key[50];
    int KeyLen;
} KeyStorage;

#pragma pack(pop)

eKeyFileRes GetNewKeyFile(char *path, UINT64 filename, KeyStorage keyStorage)
{
     char *Fullpath;

     FILE* file = fopen(Fullpath, "r");

     if(file == NULL) {
         return KeyFileRes_NoKeyFound;
     }   
     else { 
         char c;
         while((c = fgetc(file)) != EOF) {
             keyStorage.Key[c];
         } 
         keyStorage.KeyLen = sizeof(keyStorage.Key);
      }
      return KeyFileRes_NewKeyFound;
}

char sbuf[1024];
sprintf (sbuf, "%s/%s", pathName, fileName);
