我有一个char给出的fgets,我想知道如何将它转换为char*.

我确信之前已经发布过,但我找不到一个我想做的事情.任何答案都表示赞赏.

编辑:这是代码.

char *filename = "file.txt";
FILE *file = fopen(filename, "r");
if(file != NULL) {
  char line[260];
  char *fl;
  while(fgets(line, sizeof line, file) != NULL) {
    // here I combine some strings with the 'line' variable.
    str_replace(line, "\"", "\"\""); // A custom function, but it only takes char*'s.
  }
  printf(fl);
  printf("\n");
} else {
  printf(" -- *ERROR* Couldn't open file.\n");
}

我知道可能有类似的问题,它只是在C++中,我不知道它们是否相同.我有一些代码

void BuildApp(char *AppName)
{
        char *cmd;
        cmd = combine("mkdir ./Projects/", AppName);
        cmd = combine(cmd, "/Package/");
        // Make the package dir.
        system(cmd);
        cmd = "";
        cmd = combine("mkdir ./Projects/", AppName);
        cmd = combine(cmd, "/Package/DEBIAN");
        system(cmd);
        cmd = "";
        cmd = combine("mkdir ./Projects/", AppName);
        cmd = combine(cmd, "/Package/Applications");
        system(cmd);
        cmd = "";
        cmd = combine("mkdir ./Projects/", AppName);
        cmd = combine(cmd, "/Package/Applications/");
        cmd = combine(cmd, AppName);
        cmd = combine(cmd, ".app");
        system(cmd);
        cmd = "";
        cmd = combine("mkdir ./Projects/", AppName);
        cmd = combine(cmd, …
