打印Linux系统错误编码及提示
|
系统运维工程师和系统开发工程师在日常工作中，经常会遇到此类问题“当你进行了一些不当操作，系统会给你错误提示”，这些错误提示在操作系统中都是错误编码的，每一个提示对应一个错误编码，错误编码供程序代码中方便调用，接下来我们会打印出linux操作系统的错误编码及提示，如下： 一、系统环境 系统版本： 内核版本： 二、程序代码 代码如下： 三、编译运行 结果如下： [root@CentOS6 erro_num]# gcc error_num.c [root@centos6 erro_num]# ./a.out 0:Success 1:Operation not permitted 2:No such file or directory 3:No such process 4:Interrupted system call 5:Input/output error 6:No such device or address 7:Argument list too long 8:Exec format error 9:Bad file descriptor 10:No child processes 11:Resource temporarily unavailable 12:Cannot allocate memory 13:Permission denied 14:Bad address 15:Block device required 16:Device or resource busy 17:File exists 18:Invalid cross-device link 19:No such device 20:Not a directory 21:Is a directory 22:Invalid argument 23:Too many open files in system 24:Too many open files 25:Inappropriate ioctl for device 26:Text file busy 27:File too large 28:No space left on device 29:Illegal seek 30:Read-only file system 31:Too many links 32:Broken pipe 33:Numerical argument out of domain 34:Numerical result out of range 35:Resource deadlock avoided 36:File name too long 37:No locks available 38:Function not implemented 39:Directory not empty 40:Too many levels of symbolic links 41:Unknown error 41 42:No message of desired type 43:Identifier removed 44:Channel number out of range 45:Level 2 not synchronized 46:Level 3 halted 47:Level 3 reset 48:Link number out of range 49:Protocol driver not attached 50:No CSI structure available 51:Level 2 halted 52:Invalid exchange 53:Invalid request descriptor 54:Exchange full 55:No anode 56:Invalid request code 57:Invalid slot 58:Unknown error 58 59:Bad font file format 60:Device not a stream 61:No data available 62:Timer expired 63:Out of streams resources 64:Machine is not on the network 65:Package not installed 66:Object is remote 67:Link has been severed 68:Advertise error 69:Srmount error 70:Communication error on send 71:Protocol error 72:Multihop attempted 73:RFS specific error 74:Bad message 75:Value too large for defined data type 76:Name not unique on network 77:File descriptor in bad state 78:Remote address changed 79:Can not access a needed shared library 80:Accessing a corrupted shared library 81:.lib section in a.out corrupted 82:Attempting to link in too many shared libraries 83:Cannot exec a shared library directly 84:Invalid or incomplete multibyte or wide character 85:Interrupted system call should be restarted 86:Streams pipe error 87:Too many users 88:Socket operation on non-socket 89:Destination address required 90:Message too long 91:Protocol wrong type for socket 92:Protocol not available 93:Protocol not supported 94:Socket type not supported 95:Operation not supported 96:Protocol family not supported 97:Address family not supported by protocol 98:Address already in use 99:Cannot assign requested address 100:Network is down 101:Network is unreachable 102:Network dropped connection on reset 103:Software caused connection abort 104:Connection reset by peer 105:No buffer space available 106:Transport endpoint is already connected 107:Transport endpoint is not connected 108:Cannot send after transport endpoint shutdown 109:Too many references: cannot splice 110:Connection timed out 111:Connection refused 112:Host is down 113:No route to host 114:Operation already in progress 115:Operation now in progress 116:Stale NFS file handle 117:Structure needs cleaning 118:Not a XENIX named type file 119:No XENIX semaphores available 120:Is a named type file 121:Remote I/O error 122:Disk quota exceeded 123:No medium found 124:Wrong medium type 125:Operation canceled 126:Required key not available 127:Key has expired 128:Key has been revoked 129:Key was rejected by service 130:Owner died 131:State not recoverable 如果你看过nginx-1.0.10源码linux编码，里面有一个类似的错误编码预定义135个，在 objs/ngx_auto_config.h 中，#define NGX_SYS_NERR135，事实证明，这种思想是非常可取的，我们自己写软件的时候，不妨尝试一下？ rdzs.shudaoge.com/儒道至圣最新章节 （编辑：财气旺网 - 财气网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
