errno 在 <errno.h> 中定义，错误 Exx 的宏定义在 /usr/include/asm-generic 文件夹下面的 errno-base.h 和 errno.h，分别定义了 1-34 、35-132 的错误定义。

strerror() 函数依据 errno 值返回错误描述字符串，下面程序打印对照表：

#include <errno.h>
#include <string.h>
#include <stdio.h>
int main()
    int i;
    for(i = 0; i < 140; ++i)
        errno = i;
        printf("errno %d :\t\t%s\n",i,strerror(errno));
    return 0;
}

errno 在中定义，错误 Exx 的宏定义在 /usr/include/asm-generic 文件夹下面的 errno-base.h 和 errno.h，分别定义了 1-34 、35-132 的错误定义。strerror() 函数依据 errno 值返回错误描述字符串，下面程序打印对照表：#include #include #include int main(){

当 linux 系统函数出错时,通常会返回一个负值,而且整型变量 errno 通常被设置为具有特定信息的值。例如,open 函数如果成功执行则返回一个非负文件描述符,如出错则返回−1。在 open出错时,有大约15种不同的 errno 值(文件不存在、权限问题等)。而有些函数对于出错则使用另一种约定而不是返回负值。例如,大多数返回指向对象指针的函数,在出错时会返回一个null指针。文件< errno .h>中定义了 errno 以及可以赋与它的各种常量。这些常量都以字符E开头。

解决：npm ERR! code ELIFECYCLEnpm ERR! errno 1问题今天在自己学习react时候遇到了一个问题，就是在自己执行npm start运行项目时，产生了如下报错然后我自己稀里糊涂的弄了好几遍，瞎弄一通，只会产生更多的报错。最后在交流群里问了一下自己的师兄，师兄说可能是我无意间动了配置文件，也就是node_modules。解决办法：删掉项目中的node_modules文件夹和package-lock.json文件，网上有很多快速删掉node_modules的指令和方法

今天在用到_trename进行文件重命名时，考虑可能会重命名失败，需要将出错时对应的错误吗记录到日志中。从MSDN查知，函数执行失败时会返回非0，通过 errno 宏可能获知对应的错误码。为了定位问题的方便，特将错误码对应的含义列出来。 1、 errno 错误码含义 #ifndef _ASM_GENERIC_ ERRNO _BASE_H #define _ASM_GENERIC_

OSError: [ Errno 9] EBADF 表示“Bad file des criptor ”，意思是文件描述符无效或不合法。文件描述符是一个非负整数，用于标识打开的文件或其他I/O设备。在操作系统中，每个进程都有一个文件描述符表，它跟踪打开的文件和设备的状态。当一个进程试图使用一个无效或不合法的文件描述符进行I/O操作时，就会引发“Bad file des criptor ” 错误。常见的原因包括： - 尝试对一个已经关闭的文件描述符进行I/O操作 - 尝试对一个未打开的文件描述符进行I/O操作 - 尝试对一个不支持I/O操作的设备进行I/O操作如果您在编程过程中遇到这个错误，可以检查您的代码是否正确地打开和关闭文件，以及确保您正在使用正确的文件描述符进行I/O操作。
