Processing the return value of fopen is simpler and more accurate .

处理fopen的返回值更简单并且更准确。

But remember that fopen () only works with sequential datasets .

但是要记住，fopen（）只适用于序列化数据集。

Note : The " r " used in fopen indicates that the file is open for reading only .

注：fopen中使用的“r”将指示文件以只读方式打开。

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。

An example of a library function that does have an associated system call is the fopen () function declared in stdio . h.

有相关系统调用的库函数的一个示例是stdio.h中声明的fopen（）函数。

This code finds all C source files and emits the file 's name if the string fopen appears anywhere in the file .

这个命令会找到包含字符串fopen的所有C源代码文件并输出文件名。

The semantics of fopen require a complementary fclose .

fopen的语义需要补充性的fclose。

As with fopen , file_get_contents , file , and readfile , all return False on failure to open or process the file .

如fopen函数一样，filegetcontents、file和readfile函数都在打开失败或处理文件失败时返回False。

It 's a kind of cross-over between file_get_contents () and fopen () .

此方法是filegetcontents（）与fopen（）的一种交叉。

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。

Foliage penetrating ( FOPEN ) VHF / UHF SAR can image hidden man-made targets with wide-angle and ultra-wideband to achieve both range and azimuth with high resolutions .

穿透叶簇的VHF/UHF超宽带（UWB）SAR具有相对带宽很宽，积累角大的特点，能同时获得距离、方位两个方向的高分辨能力，用于探测地面隐蔽人造目标。

It shows appropriate use of some system calls and library functions from C , including fopen , fclose , access , setvbuf , perror , strerror , and popen .

它演示了对一些系统调用和C库函数的适当使用，其中包括fopen、fclose、access、setvbuf、perror、strerror和popen。

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。

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。

It is needed for the file opening , closing , reading , and writing functions ( fopen (), fclose (), fgets (), getc (), and so on ), for the printf () family of functions , and for the setvbuf () function .

文件的打开、关闭、读和写函数（fopen（）、fclose（）、fgets（）、getc（）等等）、printf（）函数系列和setvbuf（）函数都需要它。
