Of course, with the exception of fclose, you are likely already processing the return values on these.

While the C standard doesn't specify what happens without the fclose(), it's likely to leak memory.

在没有fclose（）的情况下，C标准不能指定发生的情况时，很可能是内存泄漏。

This function is a high-level way of opening a file; but, since the only way to open a file in Linux is to use the open() system call, fopen() makes use of open() in its implementation.

该函数是打开文件的高层次方式；但是，因为在Linux中打开文件的唯一方法是使用open（）系统调用，所以fopen（）在其实现中利用open（）。

The fopen methods are probably the most familiar to old-time C and C++ programmers because they're more or less the tools you've had under your belt for years if you've worked with these languages.

fopen方法可能是以前的C和C++程序员最熟悉的，因为如果您使用过这些语言，那么它们或多或少都是您已掌握多年的工具。

For example, if you call fopen ( 3), there may be no point at which any of the open ( 2) variants in the library get called.

例如，如果调用fopen（3），可能在库中没有任何入口点来调用open（2）的变体。

The DIR pointer returned by opendir() is similar to the FILE pointer returned by fopen(); it's an OS-specific object used to track the directory stream, and you should ignore its contents.

opendir（）返回的DIR指针与fopen（）返回的FILE指针类似，它是一个用于跟踪目录流的操作系统特定的对象，您应该忽略其具体内容。

Because fopen returns False on failure, this will ensure that file processing happens only if the file opens successfully.

由于失败时fopen将返回False，这将确保仅当文件成功打开后才执行文件处理。
